It's weird.
I'll be standing somewhere at times and have strange women run their hands through my hair.
And if I've just been tending a campfire, I've got that hickory/oak woodfire smoke cloud following me around and THEN things get weird.
Snuffling behind my head followed by weird growling, and there's just a harmless looking young lady standing there.
It gets really weird.
Still haven't had a good explanation for it at times, but it does seem to be a primal holdover as mentioned.
Weepy?
As in the "That's beautiful" type weepy?
Yeah, nostalgic for some unknown time & place that was so beautiful it makes me weep with longing. How weird is that?
