I'm a practicing warlock and when I was living with my parents in their house we had spirits. (I don't expect anyone to understand my religious beliefs but they do play a part in this story)
The house is very old. It used to be a quaker meeting hall and is one of those victorian red-brick mansions. When I was in college (age 16 or so) I would do all kinds of channeling - I was new to my practice and the house was a great place for it. It was just full of spiritual energy.
The first time I communicated with the spirit I asked for them to tell me their name and other simple things. Their name was "Stephen" apparently. Stephen was very tricky and sneaky though, so I wouldn't be surprised if it was not their real name. They refused to tell me their age or whether or not they were human.
Sometimes I would feel Stephen's presence physically. I would genuinely feel a hand on my shoulder or even somebody playfully poking me. I thought it was my mind playing tricks at first. On occasion when I was lying down to sleep I would feel Stephen patting me on the back, like they were trying to say goodnight to me.
Stephen stole and hid my wallet once. It happened overnight. I left my wallet on my desk and the next morning I couldn't find it anywhere. I looked all over, in every place I could have possibly put it myself. I thought that maybe I had moved it and forgotten.
Then I remembered Stephen, and I thought about asking them. I set up another ritual and asked for Stephen. I asked Stephen, "did you take my wallet?" and the answer was, "yes".
Then I asked, "can you tell me where it is?" and the answer was "bed".
I asked again, "where exactly?" and the answer was "under".
I looked under my bed and at first I found nothing. I thought Stephen was misleading me for a moment. Then I turned on my phone's flashlight and I found that it was right at the back, close to the wall.
I couldn't have possibly reached there myself, and it couldn't have possibly just dropped and slid under - there were shoeboxes and other things piled in front of where it was. I thought about whether or not it was my cat, but my cat hadn't even slept in my bedroom that night and there were no marks to imply he'd been holding it with his teeth. He has pretty sharp teeth, so it would have been really obvious. Besides, he has never wanted to take my wallet before. It would have been out of character.
I channeled Stephen again to thank them, and they said "no problem".
I said it was a clever prank and they thanked me.
Stephen just kind of lived with me as a roommate during my late teens and that was how it was. I don't really have an explanation because I never managed to convince them to tell me what they were, or why they were there.
