The Outer Limits (1995)

What really happens during an out-of body experience? Husband and wife scientists Rebecca Warfield and Ben McCormick are trying to find out by subjecting monkeys to electric impulses. They see it as pure science, but to religious groups like Family Foremost, it is sacrilege. Desperate for funding, Rebecca decides to run the experiment with a human subject -- herself. She asks her assistant, Amy, to help. Amy, a secret religious fanatic, alters the experiment. Rebecca escapes from her body, but, unless she finds a way to communicate, she will remain trapped in an other dimension.
