Like this whole journey, responses really do vary from person to person.
Some people cry (often feels like a rite of passage) and others talk about shaking beforehand from anticipation or during from the energy moving through them. Temperature shifts like feeling warmer than natural while they hug (even if it’s just a quick tap) and then cold when they step away.
Yes, for anyone wondering, runners/DMs/the less spiritually aware twin is also aware of this, but they usually frame it differently. Usually, there’s already something there from the eye contact. Then physical contact amplifies whatever was already building. People talk about feeling their energy even before bodies make contact - just being close enough creates a buzz.
Radiating is a good way to describe this. Like warmth or energy emanating outward from the point of contact. Some feel it for extended periods after - not just during the hug but for an hour or more afterward. That lingering sensation seems to be the body processing something it doesn’t have a normal framework for.
Mine seemed innocent at the time; we were all hugging, a quick hello, but then that brief contact rewired everything we both thought we understood about the world.
