Has anyone ever experienced or heard of the phenomena in which a person experiences a very momentary, yet very intense, feeling of happiness? It happened to me this morning. It was a different kind of happiness than the usual kind...if you know what I mean. It lasted just a second, but I definitely felt something... An idea that popped into my head was the random buildup of dopamine or something, that then is released across the synapse all at once, in a larger amount than usual, or something like that. Any ideas?
