I personally never had an experience of actually "seen" something but I mentioned on my thread "I grew up in the haunted house", there have been many strange events I remembered:
My brother was pressed down on his bed and unable to talk or move. I was constantly closing attic door (standard door with door knob and latch) that seem to be ajar every time I walk by and my room was right across from it.
I always slept with lights on thinking I was afraid of dark but that stipulation found to be incorrect as I have no issue walking in a dark without having a fear outside of the house.
Constant uneasy feeling when I was home.
Everyone else in the family has seen something in the house...except for me.
One thing that I vividly remember happened to me was in a dream that I had, I had an eye on palm of my hand and woke up with the hand up in the air and a half of my body being freezing and the other part warm... As to part of your body being cold has been experienced by some of them ghost hunter ppl who thinks something gone thru their body when I was watching one of them series the other day. So, my experience may have been that.
