I have recently returned to meditation and as I do kundalini yoga I decided to do chakra balancing meditation. My third eye tingles when I do more so than the others.

The odd thing is it also started to tingle whenever I see one particular person at first I thought nothing of it but I have began to notice a pattern everytime I see them. To test it out I imagined this person in my head and it seems to go off on one everytime! The only other time it tingles is during meditation. It has got me a little baffled to say the least and it never happens around any one else. Can anyone give me any insight to this?
