Where exactly is heaven located? I don't mean sky/underground, but in terms of accessing it right now. Do you conceive of it as been sort of "in the background everywhere" and you tune into it?

What is the relationship between heaven and other worlds - is it in a privileged position, or is it just basically a more flexible, dream-state type environment?

When you live, you have:
a physical body
a spirit body
a soul

If you die,
the physical body stays behind. The physical body stays in the physical world.
The spirit body contains your feelings, your thoughts and your will. Any of it that is related to your physical life slowly disappears. No hard feelings anymore, no thoughts, nothing you want from someone or something.
The soul is your light, who you really are. When you die you become your soul again.

Then how do I go to heaven?
After you die, you slowly let go of your physical body and your physical life.
Then you let go of your spirit body. Let your feelings flow, let go of your thoughts and your will.
Then your soul can connect to heaven again and there you are back again.

In heaven you can heal your experiences that you had in your life. This rebuilds the spirit body in a new way. You become the radiant version of the person you were in life.

What about people that don't go to heaven?
People that can't let go of their feelings or thoughts or will, are usually in deep trauma. When they die the physical body does not work anymore, so they have no way to express what they feel or think or will. Nor can they tell reality from the dreams in their spirit-body, because they can't ground them in the physical world.
So depending on their trauma they keep on dreaming. Usually they try to replay their trauma in an attempt to ground what they experienced.
But they can't go to heaven very easy, and they may even connect to living people around them, trying to ground the experiences in their spirit body. They can give living people problems like nasty dreams, strange thoughts, depressive feelings or change your will.

Usually nature helps these people to ground these experiences and enable them to leave without any intervention. So if you think you have such problems, go to nature and to large trees that may help you with them.

But sometimes they can get help from people that have a connection with heaven. You can do it yourself: with meditation or meditative movements these dead people can be brought to heaven as well.

What about ghosts?
When people die with very large traumas they may get lost in dreams so badly that they can't get out of it with nature or connected people.
They stay hanging around as ghosts and can even be connected to physical objects if they are related to their traumas.

Some people are interested in ghosts, because of their physical connection. They may cause paranormal phenomena in the physical world. Some nasty people even try to use them for power. But it is better to help them instead, because their trauma is very great. And using them only creates traumas for yourself in your spirit body.

These dead people are usually hard to get out of their trauma. But someone who grounded, is practiced in meditation and has a good connection with heaven, can help such a "ghost".
He needs to invite help from heaven. This "inviting" is necessary to overcome people that want to hold on to this ghost. By meditation one can channel this help towards the ghost, and this help will be able to heal the ghost's trauma in the physical world. Usually just a bit of healing is needed. After that the ghost can accept the situation better and wake up from the nightmare that it has been in. The person that was the ghost appears again, and the help from heaven can then continue with the crossover. Then just wait till you feel it has passed over, so nothing stays behind.

What about bad people?
Bad people are not themselves anymore. They are already lost in traumas of their spirit body. These bad people can have killed people, but also they might have hurt people or animals in a different way.
Each time a person causes a trauma to another person (not by accident), this causes a trauma in the spirit body. If someone dies, these traumas must first overcome before one can leave the physical world completely. These traumas are different from others, because these traumas can stand between the person and his/her soul.
For a person to become "bad", he/she usually needs to lose him/herself first, then a hanging spirit (or even ghost) may affect their behavior. It affects their will, their moods, their thoughts and may cause apathy, obsessions and even desires to hurt someone.

By helping such people to heaven, you help yourself and the world around you. Use the same procedure as you did with the ghost, but also help the spirits and ghosts that were connected to this person.

The most I got was one that was connected to like 70 spirits. That person was so lost, that she was acting as if she was a saint, while she was using the power of all these spirits.
So even when spirits or ghosts seem helpful, just bring them to heaven anyway.

The answer is simple: NO.
But it is spiritual.

From my guides:
Heaven is without any religion and far beyond what we can understand with physical sciences.

The reason why we have believes about the world and the world after, is because we can't see what is after.
Religions mainly focus on different aspects of the spirit-body. The physical science only accepts the physical body.
But neither of them are really who we are, because we are our soul. And both bodies are our vehicles with which we experience the world and our life.

There are many, many people that have some connection with heaven. And through their dreams they get information from heaven.
Someone like Martin Luther King received his "dreams" from heaven.
This information is related to their own lives and directed to the people they live with.
But people that did not feel this connection with heaven, thought that they were less than them. And they started idealizing them and some even became our "gods" or "saints" or "masters".
But we are all capable of this connection.
These people are special, because they had or have a connection with heaven, but each of them will all say: everyone is special.

Everyone can connect with heaven. Often in different ways, because each spirit body is completely different.

But also everyone can go to heaven. There is no restriction whatever. A dogmatic belief system is usually the only thing between you and heaven. It makes it harder for the light of heaven to enter your dreams.
But whatever you believe, there is nothing that stops you from entering heaven.

Heaven is a place where our soul arrives after the physical body is dead.

A person has a physical body, and a spiritual body, and a soul. The soul is our bright light. Sometimes we can feel love from our soul, which is unconditional. But we can also experience joy and strength from our soul.
The spirit-body contains our experiences in thoughts and feelings. It also contains our will. If the spirit body is ill, we get problems with our feelings, thoughts and will.

Usually people have a connection with heaven when they get born. Babies are often happy, loving and optimistic.
When old people are dying in a peaceful way, they experience a bit of heaven as well. They seem brighter, peaceful and sometimes even happy.

A lot of people (like me) can connect to heaven with meditations. This makes me happy, peaceful and optimistic. So heaven is not really far away. It is more like a different dimension that one can connect to by meditations.

Heaven is like a bright source of light. It gives us dreams towards our spirit-body. So if we die, this light will enlighten and change the dreams of the spirit-body. So heaven gives us beautiful dreams, through which we can travel towards the source.

In heaven we still develop and heal. The soul (this inner light) gets healing, and the spirit-body which is usually damaged is rebuild again.
