I used to live with my family in an old house in England over 10 years ago, I was a small child at the time. One night, when the room was dark but just about visible, I was lying awake in bed, when I actually felt a hand slowly stroke my head. I was frozen still and later turned my head slowly to see that the room was empty, with the door closed. It was pitch quiet with no sound at all.
I always knew there was a ghost where I used to live, as there were incidents every day that my brother and I both experienced, including the sound of coughs that didn't belong to any of us, and both seeing the door handle move, and waking up on the floor away from our beds most nights.
Out of all of those things though, feeling a hand touch my head was the most creepiest moment of my life.
