Could this be paranoia?

I seem to be getting scared of every little thing like if some one creeps up behind me of if some one walks past quite vigorously without me knowing. I seem to be the most paranoid from about &:30 to the rest of the night. I hallucinate in the dark, with my eyes closed and very lightly at night with the light on. I always worry at night of what I might hallucinate about. I often get unknown objects zooming past the corners, top and bottom of my eyes. Can you diagnose this problem I've had it all my life so far.
