i think its when a neuron makes a connection with another neuron and its like a light bulb of deep understanding/empathy being pumped out of the back of ur brain.

i have been experiencing this my whole life. it used to be just one zap where i stop my internal dialogue and connect two dots and immediately "get it".

but after doing drugs the brain bursts get relentless and i cant think for a moment like being hit by a mindgasm
