I've read about similar experiences on some online forums. DMT is being administered and nearby, non-partaking members are able to experience the substance. Not many details were provided so I can't relate it to your experience.
Personally I have had similar feelings of understanding people's "true essence" on mushroom trips. I attributed it to feeling their energy/vibes
I was likely smoking marijuana on the mushroom trip, if or how that may apply.
The inner soul is full of joy. Reveal my secrets and sew me whole. With each day, "I" heeds your call.
You may not care the slightest and may not be the brightest, but from here "I" sees you're mighty for you created it all.
And the jumbling sea rose above the wall.
Through this chaos comes the order you enthrall.
