Dream about trading bodies with my sister

Ok so im a man and i dreamed about trading bodies with my sister. She showed me how to take care of her long hair since i was not used to that long hair. And that was the dream basically.

However, the freaky part came when i woke up. I first thought about how complicated everything would become if this became real. And then information was beamed into me that said that my name will become "Selene".

Help?
