The complex is not a oedipus complex but what is it?

Is it an oedipus complex if your a girl that is sexually attracted to mother's or is that just a part of my ever changing sexuality. I must admit daydreaming that I am into a boy that is like a brother to me and then getting it on with his mother is a bit strange. I am hoping I am not being to graphic here and this somehow makes sense. It's just I learnt about the oedipus complex and it is usually boys wanting to sleep with mothers and girls sleeping with their dads but mine is a girl wanting to sleep with mothers does this make any sense what is this? Do I have some abstract sexuality that I don't understand yet?

Helly black-roses,

I have no idea if there is a term for what you are describing, but maybe it's a non heteronormative ödipus (I mean Freud was very.. special)

But if I understand you correctly you aren't dreaming of your own mother but of the mother from someone you see as a relative. But is this also the case for the mother?

Yes, the mother of a friend I see as relative. No I have never dreamt of my own actual mother.
