Every time I meditate while I'm listening to boxed nirvana (alpha state), I always feel a weird tickling or buzzing in my hands, my arms and in my chest. I feel like a hard pressure on my chest and a strong buzzing sensation. Like if electricity was going trough me. What is that? Is that normal?
very normal. that is the energy flowing through your body. you only feel it because you're almost too aware of yourself. it always happens when you're about to have an OBE.
