Dream about ex in car...blue fingernails?

Question

Ok so I had this dream this morning. My ex and I were in our old car and I was in the passengers seat and he was asking "but can't you at least just hold my hand?" I think I refused but I remember seeing his blue glowing fingernails. Also sometime later in the dream I had knowledge that he and my daughter were together at some Karate place (he was teaching her Karate maybe?) and that she was so incredibly happy. Then I see myself putting together or taking apart a staff and putting it's parts back into a box. What do you make of this?
