This has happened about 6 times in the past 2 months and I have no idea why. I am a 20 year old female that is both mentally and physically healthy, as far as I know. I am an extremely creative person of above average intelligence, so I figured it could have been my mind's reaction to boredom-- that it was beginning to dream while I was still awake when I was doing sedimentary activities. For my entire life, I have always had dreams that went beyond the normal level of bizarre, so I figured it was just my dreaming mind doing yet another strange thing. Additional information: For the past two years all my dreams, which I remember nearly every night, have been violent, vivid, and horrifying.
One of the first hallucinations happened while I was watching a movie in class. It was a scene where clouds were reflected on windows of a building. Suddenly, I was horrified and embarrassed. In the hallucination, I realized that I was watching a video of myself--that I was the building. I pondered copyright laws and wondered if the filmmakers had the right to film me without my knowledge. All sights and sounds I saw and heard were from the actual movie--I was awake. It's just that my mind was interpreting external stimuli in a completely different way. It was several minutes before I came to and realized I was imagining it all.
Another hallucination happened in a car ride when I was talking to my boyfriend. Suddenly, for no reason, I saw in my mind a pale nurse, around her late 20s, looking down on me. I was on an operating table. Blood and tissue covered the bottom half of her face, and I realized that she had been devouring my stomach. I snapped out of it after about half a second.
Sometimes I imagine things when I am fully alert, but lying in bed. Images pop into my mind without my control-- the first time it happened in bed it was of the profile of an Australian aboriginal's face. He silently spoke, and I spent several minutes studying the way his facial muscles moved. It was fascinating, and was the first time I had ever 'thought in images,' as I thought I was doing. Immediately after I wrote down what I saw, an image of a computer-animated fat German child eating an ice cream cone popped into my mind. After watching him for a few minutes, I thought to myself that it was a good thing that no bad scenes had occurred in my mind, because I had no control over it. Instantly, I saw a skull with bulging eyes snapping its jaw and rotating towards me, then away, again and again. I suppose that reaction meant that on some level I was controlling them, but I have no clue how.
Once when lying in bed, I imaged a life-size humanoid puppet that lay rotting and dying in a bed like mine. It watched me with a most peculiar glare, which disturbed me so greatly that I wished it would die.
Why could this be happening to me?
