I need some help/opinions plz!

Hi, all.

Ok, a close friend to me told me that he had a nightmare-ish dream last night, about me.

Few things you need to know before I start. First, in real life I'm an artist. I love to draw, I make white and gray illustrations. Second, my ex-girlfriend that is in this dream is a witch (this is a believers part) and she still has a solid crush on me.

So, the dream...
he told me that we were in some kind of a forest, with curved and weird trees. The ambiance was kind of dark-ish. Now, the interesting part... My ex-girlfriend was there too. My friend, my ex-gf and me were sitting on a table and i was showing them my illustrations. Suddenly, i showed them an illustration of Medusa. (also known as a Gorgon...in greek mythology it's the girl with the snakes on her head) So, he remembers that, as soon as he saw it, there was a scream that came of no where. He felt a fear and he woke up. Next thing i know is that he calls me at 2am to ask me if I'm alright. I told him it was just a normal nightmare... but now, that i think about it, I'm not really sure.

1st my ex-girlfriend was there, and this is weird
2nd what's with the Medusa and the weird atmosphere....?

If anyone can help it would be much appreciated. thank you in advance.

PS: don't respond if you know you'd talk sh**! thanks
