Strange straight vs. lesbian dream?

Mmmmkay, I had a strange dream last night obviously. It started out with me riding a bike, I never ride a bike.. haven't since I was around 7, anyway I was riding the bike and there was a guy, very attractive if I might add, by my house but apparently I was familiar with him. My bike broke down and I carried all the pieces towards him laughing. I'm usually a lucid dreamer, so right now I had no control of what was going on until we went into the garage and we started kissing.. ok.. so then the lights go out and I pay no mind until I open my eyes and realize I was kissing a girl, a very attractive girl too. In my dream I thought nothing of this, my stepdad was fine with it, my mother was furious that I was "together" with a girl. Then when I woke up I realized, when I first kissed the person they were a guy.. after I did they were a girl.. and I've had questions about my sexuality before and I don't know.. maybe it wasn't even about sexuality and it was just symbolism? any ideas?
