Weird Sensation

[Vytas]

Hello guys. 

I wanted to ask you one thing for a while but was postponing. Well now i am doing it.

Here it is: around a year ago i started to notice some weird fewling/sensetion in yhe body. It appeared more commonly when after reading Echart Tolle's book about now i started implicating it. For example when i sit in front of computer or when i lay in my bad and remeber to be here now, pay attention to my breath i feel this tingling. It feels weird. Most often i feel it in my legs or hands. I also notice it appearing when i watch video about enlightnment or some inquary video. Is it some sort of power waking up in me or just muscles going crazy? Maybe this sensation is always in my body and i am just not aware of it on minute to minute basis. Maybe it is intuition that tries to tell me smth through my body, idk. Maybe you guys experience smth similar and could help me understand what it is? 

(Btw sorry for my English)
