Since I was a child I have always experienced noises in the next room or small things being moved. Yesterday I was home alone sitting on the couch when I heard several loud noises. I chose not to investigate right away because it always makes me feel a bit anxious. I left about twenty minutes later. Shut and locked the door. Then about an hour later my neighbor called me worried because my door was wide open. She shut it and when I got home it was once again locked and she doesn't have a key which you must have to lock the door. I checked out the bathroom. My blow dyer was on the floor and all of my shampoos and soaps that were on the edges of the tub were in the tub. Things like this are always happening to me. I have had my homes blessed, I have had someone burn some incense ( I didn't ask many questions) Why does this keep happening?

Well, it keeps happening because incense doesn't have authority over spirits. Having a house blessed CAN help, but I might argue that it would be weaker spirits that it would affect. If a spirit remains somewhere, it is because it has legal(spiritually speaking) rights there. Spirits vary in their degree of power and wickedness... some will put up a big fight... some will go quickly. Like we have out physical and natural laws of nature... so the spiritual realm also operates. If you want this thing gone, assuming it really is a spirit... you have to operate in spiritual laws.

Is there any other reason you might suspect it is something paranormal? Have you ever seen anything or do you just hear noises?

Just because it's there doesn't nessicarily mean it wants to harm u. To me it seems it feels ignored so it said "hey look I'm here" Many times when people say they think something's there, but in reality they know it's there. No one can tell u that those little hairs that stand up on the back of your neck aren't real. I really don't know much about getting rid of a presence but many times it is possible to co-exist and lead a perfectly healthy normal life. Its kind of like having a cat I guess.

A very deceptive cat. True they are not always how for "physical harm". Passive harm is worse because you're not aware of it.
