Nothing, I just ignore the sounds and co-habit with ghosts

I sleep facing the wall precisely bcs of this. If I see it, it's not like I can do anything, so better to be blissfully unaware and pretend you don't see/hear/sense anything

Maybe they can help

My boyfriend heard someone walking downstairs at 5 am when he was sleeping over, I told him it was just the dog, not to bother me. The dog was actually in the yard most of the night LOL oopsie
