Last year I was touched in the hair. I was trying to sleep at
around 9:30pm, lying on my right side, left side (back) facing the
wall. Bed's head was against the other wall.
Then this stroking sensation, at my hair above my left ear, like
fingers running thru hair. At first I stun for a while, wondering
what that might be. Strangely I was calm, but freaked out and slept
with the lights on til morning. I'm a member of a paranormal group,
so I suppose I can accept such stuff to an extent without over
reacting 
2nd night, happened again, this time lighter sensation, also while
lying in bed.
3rd night, yet again, this time as I was doing my
homework.
This time just a slight touch.
I have a friend with the gift of spirit communication and third
eye. Had to ask him to ask the spirit to leave.
