I do not know of Marie having a particular cure for this. My response would be that the door is only a door while it is open. Keep the doors closed while she is asleep. If any of the doors is directly pointed at the bed, try to place some object that will slow the energy flow down. For example, when I travel and end up with a strange hotel room arrangement that has the foot of the bed facing out the door, I place a suitcase on a coffee table and place it at the foot of the bed. It seems to work fine - I've had much better sleep quality from that.
