Is it normal for you and friend to have same sexual dreams?

Here goes. I am 24 female. I have a live in boyfriend. This has kept happening to me for the last year and it is very disturbing.

I will be asleep, wake up, and I just had a very sexual dream involving one of my guy friends. Specifically I will have been kissing him, giving a full body massage, then oral sex, and sometimes it leads to sex in the dream. It all started with one friend in particular, we will call him Seth. After I woke up from this insane dream I got a text message from Seth. I thought it was weird. But I read it and it said, "Holy shit. I just had the weirdest dream." He and I have never discussed anything remotely sexual so I didnt think he had the same dream as me. I wrote back and asked him what it was about. He called me. He told me the exact same dream I had. Now this same scenario has happened 4 times in 2010 with my friend Seth.

Another old friend, Scott, it happened once this year.

Another friend Alex this year too. But now Alex won't leave it alone and randomly brings up the idea of making the dream happen.

Now I just woke up and it happened with my old roommate Luke. He just texted me too. After telling me and I was like omg all he said is LOL.

This has all happened this year in 2010. I have not told anyone else about this happening. None of these people are friends or know each other. They are all from different social circles. No, I am not some kind of witch or wannabe witch who has casted love spells. I don't know what is going on but it is very weird.

IIN? Any advice?
