Just had a crazy encounter with it again last night wasn't too bad just weird. I woke up unable to move again and though to myself oh no not again (tried to think of some good things but it didn't really work) Anyway i knew something was in the room with me but it was a little bald thing reminded me of the thing off lord of the rings and it was just climbing around my bedroom wasn't causing any harm just looked lost it was really strange then it just kind of slumped itself on my clothes and just sat there looking depressed, but then it got scary because it looked at me as if it was studying me then just sat at the bottom of my bed and it was saying everything i was thinking, for example i was thinking whats it doing? Then i would hear Whats it doing? pretty strange but at least it wasn't that scary just weird glad it didn't try attack me though haha i thought that experience was pretty cool to be honest.
