I was reading up on
ASMR and it reminded me of something I felt when I was younger.
The only way I've felt this is by rolling something very tiny between my thumbs and index fingers. For example, rolling a string or piece of paper into a very tiny ball. As soon as it becomes compact or small (I have to be rolling it tightly), I get this... tingly feeling. it starts in my fingertips and spreads. It's like overstimulation and it's hard to continue rolling this tiny object between my fingers.
Am I crazy or does anyone else ever experience this? I can still reproduce this feeling. Give it a shot. I know that not everyone can feel ASMR.
