I cannot get over this feeling that I am being watched constantly. I can hear shuffling in the walls at night while I am drifting off to sleep, and have noticed different pieces of furniture slightly moved a few inches over the course of weeks. My family thinks im going insane but I swear to you guys i am completely lucid and sane. What should I do?
