Since months ago unusual noises and shadows have been seen in my apartment but we didn't pay attention to any of it because we thought it was our imagination. It was only recently things have been getting very very strange. About a month ago I was working on my computer when I felt someone touched my right shoulder, I turned around to my right to see who it was but there was nothing, I go back to my work when I feel the same touch on my left shoulder, I turned around to the left and there was nothing again. I thought someone was messing with me so I yelled and got up from my chair only to see there was no one in the room at all. I forgot about it until today that I had brought very important papers from school that I had on my desk. I left for a couple hours and locked the door so the cat wouldnt get in there and mess with stuff, when I got back these papers were gone. Now the papers are of vital importance to me, I really really needed them so I started to freak out. I looked absolutely everywhere just to find them hidden in one of the drawers I never use. I dont know what to make of any of these. If there is anything in my apartment is there a way to find actual prove? Any methods or tricks to get evidence of paranormal activity in my house? I hope I can find some help here or someone who has had experience with this kind of stuff.
Thank you!
