Sleepwalker certainly makes an attempt to be a mind bending thriller, and does so with mixed results. The viewer might have to watch the film twice to get the gist of its meaning. I did!
A woman is found sleepwalking in the middle of the night and has no idea where she is. The police find her and return her to her dorm. She has a history of sleep walking and is concerned it is starting again. After another nights restlessness, she decides to go to the College sleep study program to be monitored.
After the first time she does this things start to become strange. Things around her start to change subtly. The Dr. In charge takes a personal interest in her case and attempts to help her as things progressively get stranger and stranger as the studies continue.
The rest of the film is an exercise in uncertainty, nightmares, and amnesia. The film, I thought, was somewhat thought provoking but misses the mark as a real mind bending thriller. It is more a film about a woman with a sleep disorder which turns into a mix of confusion, hallucinations And scattered reality.
I would say it worth a viewing but don't expect much in way of a strong thriller....
