can anyone explain what just happened to me?

[suburbianmonk]

I have been meditating for over a year on and off and I just now started back up on a daily basis. I recently was meditating and I lost track of my breath falling into a what I believe was a dream or possibly a vision of some sort. But a little while into the dream or vision, a bursting sensation occured in my head and my eyes shot open. It wasn't painful, just extremely suprising as I have never had anything like that happen when I fall into a dream/vision during meditation. If anyone can help or has experienced anything like tjis please let me know. Thanks and God bless!
