[@Caits] Sorry to be a pest, but Imma need more room then a corridor. If the mirror needed to, could it create a 'room' that the audience could see into with lacrima or on a giant lacrima screen? Some fears need space, like those possibly related to memories.

It doesn't have to be a mirror, not does it have to be a corridor. You can have as much room or as little as you want
