Strange feeling in my hands?

I'm a 15 year old girl and I've noticed a strange feeling in my hands recently like I can move them but when I do it dosent feel like I'm doing it e.g. If Im tying a knot I can actually tie it but I can't feel myself doing it like I'm watching it but not doing it myself I can still feel texture and heat on my hands but this felling is happening allmost everytime I do anything and I'm really confused please help
