Hey this is my first post on this website!
After reading most of these hallucinations they have sparked my memory from when i was a child.
I vividly remember seeing a LOT of spiders and insects crawling on me (i was about 11) then id wake up trying to brush them off and being really paranoid thinking they were actually on my bed.
I have also half awoken to have a look around my room and seeing someone, this scared the crap out of me and after second glance it was just a few things in perfect place to give a silhouette of a person!
These are my hallucination type things that i remember haha :)
