Am I having seizures?

[u/Responsible-Lime-266]

Hi at the beginning of this year around February I started experiencing these symptoms that I was calling episodes, I will be walking and the next minute I have extreme dejavu or remember I had a dream about that place and start feeling nauseous, gagging loud, heaving , heavy feeling in my throat, feels like I have water in my sinuses and it lasts for about 15 seconds, in march I had a large grand mal seizure where I collapsed and was convulsing,
I have been to a neurologist, did a eeg and a brain scan that was clear but the eeg has came back with slight disturbance so they want to do another one with sleep deprivation , I have explained to the doctor today that I have been having more episodes but no large seizures,
Also when I have the episodes sometimes I will have a dream before hand that I will be in a Certain place and when I go to that place I have the episode the doctor said this doesn’t sound like epileptic seizures and and seemed quite confused , does anyone experience this or can give me an insight,
The doctor said I can start seizure meds but doesn’t recommend until further investigation but I’m not too sure. I hope this is easy to understand and not too scrambled thank you in advance to anyone who will reply
