energy shock!!!

[lord.easton]

hey everyone I am making this post because I am curious as to what sensation I am feeling ? why it is happening ? is this a good thing or a bad thing . so lets get into it . first I am doing exercise's to raise my energy the alternate nostril,hatha yoga and kundalini yoga this is nothing new for me at all!!. every now and then I go to sleep like any other night and all throughout that rare night .I feel some bioelectricity like I do when I'm up but this is way,way,way   stronger it feels like an huge energy field around my lower body . it is like energy shocks all over the lower part of my body legs and feet. before when this first happened it was usually my feet  only but last night it was my feet and legs and I also am reaching down on my lower  body slapping/swatting it because I also get  strong crawling sensations but when I go to get "it" off me nothing is there lol. I have felt the crawling and really strong energy before but that usually only happened when I did the above exercises two times in a day and went to sleep but I did not do that yesterday or anytime else lately and I still felt this going on last night . so obviously this has something to do with me raising energy . but what I need to know is what this means . has anyone of you ever gone thru this ? . I cant understand what to make of this and why is this only my feet or my feet and legs when this happens ?. why not my whole body then?. not that I'm super disappointed about this like I said the energy shocks are aggressively  strong lol .so I can hold out for and while . but why is this happening should I be concerned about this? what does this say about my power is it stronger . I want to know if anybody has been through this I am super curious .I can not wait for some feed back and please  If there is something you feel you need to know more about  regarding this don't hesitate to ask me 
thanks in advance
