That was weird..

I was lying in bed, fell asleep then half woke up and my hand was completely numb, so I moved it and I could feel all the blood rushing back but I was full on spaced out and felt like there were tubes in my hands shrinking and growing, over and over. But then I thought, maybe it's just my veins having the blood pumping through them.. and I'm overreacting. But should you be able to feel that? :/
