Cool story, I've had that before when you look at someone and they look back and you both realise each other are baked and there is some connection between you and them :smokin:. I sometimes sing along to music walking about providing there is no one around so I don't look mental hehe

By the way that colour thing when you listen to music is called synesthesia, a mixing of the senses, you experienced/have sound --> colour synesthesia.
