You are transported back into the main room. Your memory of past events within the house becomes fuzzy, as if a dream you were woken up from too quickly to recall. You try to exit, but the door is still locked.
The door on top of the staircase has been bricked up in your absence. A closer examination proves you can't enter it anymore.

You can still choose the door on your left,

the door on your right, or

the door underneath the staircase.
