Mind Monitor

I believe I was lucid dreaming, or at least vividly dreaming, during this time period.

I was interested in what was happening with the gamma waves. They increase and then decrease, and then increase again. There's a cycling of maybe "bursts" or "spikes"?

Is this to be expected during dreaming? I was trying to find studies with more detailed information, but didn't have much luck...

Thank you everyone!
