I was about to say, yeah that, in general people like hypnogogia because of the boost it gives to visualization
From what you describe, I have a hard time thinking it's actually hypnogogia however... it sounds more like you're describing mind-wandering (being distracted and having visualizations/thinking)
If it's hypnogogia, it means you literally are seconds away from being asleep... you said it happens while sitting up on the floor, which is what makes me think you're describing visual mind-wandering/distraction
Most people's minds wander too while they try to fall asleep, but that's not hypnogogia... hypnogogia also only tends to last under a minute or two, and is often only a couple seconds long, immediately before or after sleep. Your mind can wander for pretty much as long as you want.
Hypnogogia is like a thirty second acid trip (edited)
I cant really say its mind wandering cause it doesnt really wander when Im very focused, Im able to go about in a first person perspective pretty easily in my wonderland right now and I dont really see anything going off. The reason for using hypnogogic is cause I have similar experiences many times when going to sleep, yea its like an acid trip, random images its just so random dream worlds Im juming into and out and I think that is hypnogogic if my definition is right.
