I felt something like that when I meditated for a long time, except it was more of a buzzing sensation that was on the top-rear area of head. I also felt a feeling of intense focus and confidence, like everything I did was right and really smooth.

I was watching the youtube channel Big Think a few weeks later where they had a guy on there named Steven Kotler and he talked about this phenomena he's researching called "Flow" and he described everything I felt.

People can sometimes enter this state while doing an activity, where the brain's calculation activity goes from the pre-frontal cortex to the rear of the brain (the part that deals with the subconscious) and its almost like they gain super-powers but it's just the brain entering peak performance.

So while maybe it's not exactly what you experienced it was similar enough that it reminded me of when I had my own weird little brain trip.
