Energy Tension Spots

For years I have seen shadows in the form of people and I have been able to sense certain areas of a house, for instance, that seem to have a really high amount of tension.

For example, my house has two spots- one in the living-room and one in the downstairs hallway. I usually see strange things near those two spots.

One night as I was walking past the spot in the living-room, and image of a half-man half-goat flashed into mind, and I felt like the tension in that area was directed at me. About a week or so later, during the finals, I looked up to see a little boy peeking over the shoulder of the girl in front of me. He disappeared, and when I looked around the room I didn't see him anywhere.

Also near those spots in my house (and a spot in my best friends house) I often see small black or white blurs that look like they could be animals.

My friend has also described an experience in which she too, saw shadow people. Does anyone have any idea what's up with the shadow people? Does anyone else see them? Does anyone have any theories on what the spots of tension may be?

I thought for a while that they could be spots where there was a buildup of energy- but it's not a good energy. Though sometimes it seems more tense than usual and its generally then that I see things, with the exception of the black and white blurs. Those show up randomly, and seem to be harmless.
