A bit similar to this question, I did experience, twice, something, that I would qualify of, pretty weird.
A feeling of being gigantic, it was very very disconcerting.
Like, you look around you and you feel like everything around is you is way way way large, like if yourself you were being a tiny ant.
Then again, you may experience that your body is a mere gigantic vessel in which you, tiny entity, would be trapped in.
I did also experience fear at that time, of moving, of things. Because they were so gigantic and could "hurt" me if they'd fall on me for instance, etc. It also induced me dizziness.
Ultimately it wear off after a while. I do not do drugs, nor consumed anything.
My question is: Does anyone else has experienced similar and what is it called like? (Finally, could someone explain it to me?)
A few searches online yielded poorly results.
I do suspect that fatigue was at play but I can't link both together for sure.
