So, have any of you noticed a decreased need for sleep when sitting? When I was moving through the Jhanas during my Theravada time, it eventually got to be so that I only needed 2-3 hours of sleep on any given day. When I stopped doing that and began Shikantaza, though, I moved to a more "normal" sleep cycle. However, very slowly, I'm noticing that I have more energy with less sleep again.
Just curious if any others have experienced similar phenomena. Or am I just abnormal (wouldn't surprise me in the least)?
