Yes I believe I have, as I have lived in 2 haunted houses in my life. When I was 10 yrs old I (several times) saw an old woman walk thru our kitchen. Once I saw her sitting at our kitchen table, and she would be in the window, as part of my reflection if I was looking in/outside. The house where I saw her was very old, probably about 120 yrs or so.

The other house I lived in when I was in college, we could feel a presence. The answering machine would turn on and record when it was unplugged from the wall. Lights would "pulsate" like a heartbeat, and little bolts of lightning (possible high charged static electricity) would shoot out of the mirror when you would walk past it down the hall. I was sitting on the couch, the tv was off, and I happened to look at the tv screen and I saw a man sitting next to me in the reflection of the screen. I really FREAKED out!! I was home alone at the time and it was dark out, but I ran out and sat on the sidewalk until my roommate came home 2 hrs later!! I was always freaked out by these things, but now I'm 42 and nothing really bothers me.
