P waves

Last night I felt a wave go through me kind of like a tingling with a warm sensation. As it traveled through my body it almost gained in intensity. What is the biggest bummer of the whole thing was when it got to my chest area it was so intense I had to end my session because I could not take it no more. Do these waves get lower intense as time go on? Or do I get used to them? Not sure I could let them go all the way as intense as it was.
