Strange Experience.

When I was a Senior in college I had a weird experience. It all started in May after finishing finals for the Spring Semester. I was reading a book and it was around 7pm. I got up to get a glass of water. In the hallway I noticed that there was a hard to describe cloudy filtered light hazy spot in the hallway. Sorta like the Star Trek beam up when you are unable to see the person just the haze or whatever you call it. Anyhow, I pointed this out to my brother but he didn't seem to think much of it.
So I wasn't too concerned I got my glass of water and went back to reading. Little did I know this was just the beginning of a weird week for me. "It" or whatever beamed down would touch me but "It" could not be seen. "It" did draw pictures on my jeans and even in the grass when I went back to college for the summer semester its very strange. The touching has stopped but it does come back at times and I can feel whatever it is touching me again. Has anyone else experienced this?
One picture was a happy face, a deer and some other pictures I don't remember. My friend could see the deer drawn on my jeans so it wasn't just an hallucination.
