I've experienced it several times, all of the times on runs over 80 minutes long. Basically, it feels like you're a seven year old.. you start getting these flashbacks into childhood where everything was calm and peaceful.
I remember the first time I had the high I flashbacked into my 8th birthday, where my parents bought me a radio as a gift and we went to my grandmother's house and there was a lot of sun, and everything was so warm and fuzzy. I ran for a couple more miles, came back home and noticed that everything was warm and fuzzy there too. This was a night run, so I slept/dosed off in the bed through the next day and woke up around 2-3am 24 hours later.
That's when I was hooked. That's also when the shit started going wrong.
