Why do people just get goose-bumps out of the blue? Because I do and it’s kind of freaky!?

Answer 1

Some would call you a 'sensitive'....possibly on your way to becoming an 'intuitive', (perhaps you've recognized this within yourself already).

I would say don't fight it, don't suppress it, just go with it and learn from it...it may even keep you from harm in ways you might not realize at the time.

Blessings...

Answer 2

Usually because you're cold or scared or someone's touching one of those sensitive bits... like your earlobe. I get weird twitches out of the blue like Tweak on South Park - I wonder if my excess caffeine consumption has anything to do with it...
