A movie about four or five people going into another man's mind on different levels, I remember it was filmed in a snowy climate, in a building where they could invision going after this guy, who was a bad guy, and going down into the guys mind at different levels of consciousness. It is driving me nuts trying to remember it.I think they were trying to get some kind of information, at one point one guy met his wife (who was dead I think) at one level... oh jeeze, not clear on this, but she tried to get him to jump off a ledge with her, as she apparently had at one time...

Inception?
