Sleep Hallucinations. Normal?

So I have anxiety to begin with and last night I was talking to my husband about a fear that I have of "losing my mind" or becoming bi polar or schizophrenic before the age of 30. He of course thinks that the notion is ridiculous and rather scolds me for dwelling on things like that. The irrational fears that I carry are a product of the anxiety and I know it but it's still a vicious cycle. Okay, so being as the idea of "crazy" scares the hell out of me I decided to watch a documentary on severe schizophrenia in hopes of overcoming the stupid fear. That of course scared me more and when I went to bed it was all I could think about. How "f**ked these people were". I get hypnogogic episodes briefly at times where the room looks totally different momentarily, or the jerk where you have the sensation of falling. I jerked awake and rolled over and briefly saw the shape of what could have been passable as a human over my husband who was beginning to stir in his sleep also. The image was for only about 1 and a half seconds and quickly dissipated. And then my husband sat up in a coming out of sleep phase and points to the shelf next to the bed and starts saying "Radio, I've never noticed that radio there." Which is funny because the radio has been on the shelf by the bed for the entire time we have lived here. Do sleep disturbances such as these that I described occur from an over anxious mind? They don't happen to me all the time but it seems like the more stressed out I am or the more exhausted they are more intense.
