That sounds reaaaallly suckish.
Is it one of those things like "d'you say sommin?"
or is it like the video
I'm not sure what you expect, haha.
It's a hallucination, so it's really confusing and sometimes scary I guess, but it's not always necessarily like the video. It could be, of course.
If you want to know what it's like, go without sleep for awhile and you'll start to hallucinate.
