Sorry for bumping this old thread, but I would like to say that the same thing happens to me.
However, it does not occur during meditation (I don't meditate). It has happened to me since the age of 14. During my teens, I would feel a sort of tingling, tickly feeling on the centre of my forehead just above my nose, sort of like what it would feel like if someone was pressing the area with their fingers. This happened every night nearly just before I went to sleep. It happened even after I left home and lived in different houses.
Now I am in my mid-20s, I don't get it so much, but I still do sometimes, on and off. For example, the other day I was sitting reading a book and I started to get the tingling feeling. I should probably say that I started "hearing" jumbled up, incomplete sentences in my head at the same time.
Anyway, I see there are other threads on this topic and I will read with interest. I have asked people in my family if they ever get this, and no one does, so it is nice to find that other people have the same experience.
