I'm going to apologise in advance for being very vague and potentially incoherent. I haven't told many people about this sensation, but not a lot of them seem to understand. I don't think I'm particularly good at explaining it. This might sound like woo, but I assure you it is nothing of the sort (at least I think it isn't).
Essentially, some very odd things set off a pleasurable tingly feeling in my scalp that can sometimes be powerful enough to make me lose focus on everything but that thing. Other people apparently experience it too. It's hard to say what sets it off. It could be anything, although it often starts when I watch someone do something meticulously with their hands like carpentry. But there are others. Once it was the sound of the tree leaves rustling in my grandparent's garden and another time it was the eerie dialogue in a cartoon about Mark Twain's stories. I've even had it from watching a two second scene in a film. It isn't sexual at all for the record so I know it isn't a fetish.
I've had it since I was 4-5 and if I think about a certain memory, I can experience the feeling. I often try to do it daily. I also find myself occasionally drawn to mundane television/film scenes, odd sounds in music or public demonstrations of something intricate in order to experience it.
I'm going to leave this link here to a story about it.
I first found out there was actually a community for this about three-four years ago. Back then there weren't any news articles about it and there hasn't been any scientific research into it to my knowledge. But reading other people's experiences has proven to be an eye opener for me. I was pretty surprised to find out there are people who also actively attempt to experience that weird feeling. A lot of their stimulants have no effect on me, or feel downright creepy to me, but in The Independent article the writer states she watches shopping channels just to get that buzz and I totally understand that. I do that too with other mundane things which I won't delve into because they're awe inspiringly cringe worthy.
So has anyone here experienced anything of the sort? Does anyone have any possible explanations for it?
