Ghosts or imagination

I was sleeping in my bed when I awoke. It felt like someone was holding my face down with a hand or something. It stayed like that for about an hour. After that I thought it was my imagination. But about a month later I was standing in my kitchen doing dishes. I also had the t.v. on. The t.v. was on channel 39. When all of a sudden the t.v. changed to channel 40. I went looking for the remote and the remote was on the entertainment center. Then about a couple of weeks later I had some friends over. They were sitting in my frontroom playing Nintendo 64. When all of a sudden my touch lamp came on all by itself. Then about a month after that my girlfriend and I was sitting in the front room watching t.v. when we both heard my gate open and shut. Then we heard footsteps walking up my steps to my patio. We also heard voices coming from my patio. I went outside when we heard the voices. I searched everywhere but there was no one out there. So I know I was not imaganing it because there are witnesses to some of the insidences.

It makes me a believer in the after life.
