In Tibetan Buddhism there is the concept of the bardo, or interval, the intermediate state ('gap') between one life and the next.
The term can also refer to other transitional spaces, even the space between birth and death (i.e., 'life').
Taking this concept as inspiration filmmakers have explored the possibilities as drama, sometimes referencing the psychological demons and obstacles presented in the Tibetan Book of the Dead and sometimes taking great poetic license. The resulting films are often labeled 'thrillers' or elude categorization.
