Okay I don't believe in ghosts, or demons or angels or palm reading... I am the queen of non-believing, but I have an imagination you wouldn't believe when it comes to creep outs, and I have lived in more homes than anyone should... so I have plenty. So here are just a couple.
Here.. our basement has two extra rooms with doors which will not stay closed... they are cold, dark, filled with cob webs and who knows what else, and have dirt floors. I hate that basement and tend to run down, do my laundry as fast as possible, then run up the stairs. Sometimes there is light coming out of the basement when the lights are all off!
We had an apartment a few years ago. (someone else mentioned a place just like it, there had been a store underneath and two other little apartments upstairs) We moved in, I spent about a week sleeping in the bedroom, then found reason to sleep in the living room for the rest of the two years we lived there. I had nightmares that there were demons in the bedroom, and I was freaked out about letting the kids use the room even for toys. This was also the place we were in when my older two had a ghost friend and other scarey ghosts which they would press into the wall to make them go away.
When I was a kid we moved into a big house and it had a built in hutch in the kitchen. If you walked into the hutch and looked up there was a door which led up to an attic. I was terrified and curious at the same time... I never opened it though... guess fear took over. We heard noises from up there, and my mom was sure that the guys who had been taking care of the house before we moved in had continued to use that room after we moved in. (two very creepy men) She made the landlord change the locks... and we never heard the noises again.
