It's hard to tell from the picture, but I'd guess it's a lacewing.

Hygeine

I believe that is a tarantula.

Or a green lacewing

Great white shark.

Either that, or a grizzly bear.

It's body is really skinny and straight, the wings are almost invisible ( I'm a bad describer ) and it has two antennas on its head that are constantly moving, the insect/bug thing is really small. I thought it was a piece of grass. (Sorry for the bad picture, it was on the ceiling and was really small)
