We were doing Body Scan Meditation. He was instructing me to breathe in deeply and imagine the breathe being channelled to different body parts. First it was to breathe in to my toes. Then to breathe in to my foot. Then shin, then upper leg. 

I found it incredibly difficult to make myself 'feel' this. I was concentrating so hard. I did deadlifts and squats only yesterday. Yet I could not feel my legs or arms without tensing them or punching them or moving them around.

I could however easily do it to my hands and face. And bizarrely only after doing it to my eyelids could I suddenly feel my arms and legs.

Does this count as depersonalisation/dissociation? Is it really not normal to not be able to feel my arms/legs much if I am sat relaxed?
