Some people wake up in a house, They all find out that they had died, And they wonder if it is heaven or what. Could you name the title of this movie please.

Sounds like Beetlejuice.

No beetlejuice is not my favorite character lol.. that ugly thing. Lol.. no these people wake up in this house, they can't go out of the door, the windows won't open and they all find out that they had died and they wonder if the house is heaven then.
