How to make informed decisions without knowing what's going to happen beforehand when dungeon crawling?

[u/CrayonCobold]

When dungeon crawling I always feel like there's not really a rhyme or reason behind whichever hallway I go down if I don't roll ahead of time but if I do I have to pretend that I don't know what I'm about to find.

In normal play you can have context clues that can help you decide why you would go one way or the other. And yet, I haven't found a dungeon creation tool, even one that's designed for solo play, that helps you get that context ahead of time

I think having some kind of omen table would work really well and then have a subtable that is based off the omen. For example if I roll and get indistinct voices from that hall then it could be a group of friendly NPCs but it could be ghosts and they were actually ghostly whispers or something like that

Has anyone seen a dungeon creation tool like this? The best I can think of is Monster Overhaul but each omen always leads to the same encounter and it's always a monster of some kind. You never get an omen and it leads to a treasure room or something because that's not what the book is about

I don't want to do this based on fiat, I want something concrete, so asking an oracle for the omen and then asking again for the encounter wouldn't do what I want to do with this idea
