This is an update to Meditation Update 2/18/16
Had a similar experience, but this time the energy sensation was a lot subtler.
I noticed that I was breathing out of both sides of my nose (usually I only breath through one or the other nostril), my body was again distant, and seemingly “stiff”, I also felt the it cool.
I was not as excited this time, and stayed in this state for a while (a few minutes), it was a very content/relaxing experience.
Unfortunately my Insight Timer (set for 1 hour) went off before I could go further.
I am going to set Timer for 1:30 hours from now on, and longer as is warranted.
