Hey asala.
No your not crazy. Sometimes when lying on my bed, looking up at the ceiling, (somewhere between sleep and awake), I see visions of dots dancing across the ceiling, or fishy scales, or gigantic spider webs(though there arent any in my room thankfully). Not full pictures, just images. And I am not on any psychedelic drugs either, lol.
FYI: Oh by the way you are my #1 myspace friend. I know who you are, do you know who I am, muahahahaha.
Luvs.
