No 1. is meh to be honest- I only open my eyes like that if I've had a rough time the night before and fear the light hurting my eyes. 🙂
No.2 is really creepy though. I don't have any big mirrored spaces in my bedroom- I also have this weird feeling that mirrors do strange things at night. Completely irrational.
No. 3 is just utterly sad and depressing. Imagine if the afterlife was like that- just a hollow reflection of other peoples dreams. 🙁
No.4 has actually happened to me. 😱... Although it was just a stray cat liking my warm bed and not an actual person- still gave me a bit of a fright though. 😀
Seriously, I have to stop looking at these threads of yours, I still have the occassional thought about those terrifying giant teeth you posted. 😉
