Goosebumps on my lowerbody when I touch my abdomen after practice

[Scholar]

So I've been doing some qigong exercises every day and sometimes I do accumulate a nice amount of "feeling" on my hands, and, when I touch my lower abs I feel goosebumps on my entire lowerbody body.  Also, I feel those on my shoulders and arms when I touch my pecs.

 

Does anyone knows what it might be? Is it energy related?

 

Thanks
