Hand 'wakes up' from SP after the rest of my body. is it possible?

[Beefer]

Hi there, I have been practicing WILD for a few days now and at today's morning I WBTB like I got used to and as I am starting to feel that my body is relaxing and becoming heavy ,I am feeling that I have to scratch my head. So I scratch it with my right arm and logically it doesn't feel relaxed or heavy anymore like the other parts of my body. After 7 hours of sleep I got up and realized I failed the WILD (doesn't matter I will succeed today ). Then I noticed my right hand is not moving like the rest of my body. I RCed and it was the reality so I tried to move my arm and it was numb. After less than a minute it moved properly. The thing is that when I 'woke up' my hand it had the same feeling as waking up from SP. So I was just wondering if there is a chance that because my arm got into SP after the rest of my body due to the scratch it also woke up later? Have this happened to someone here or I am alone ?
