What is being in the flow?

Can trauma 'float away' 

Interesting article ((( Time ))) Mental health and salt water flotation tank sessions.
We had had similar experiences with Deep Relaxation - Neutral Space Relaxation® 
an experiential feeling likened to the quality of 'single plane' while in the flow. 
Can we hold this feeling more..... ?
Have you had this flow feeling? 
Let us know.
