What does it mean? Why can't I remember?

What does it mean? Why can't I remember?

I dream about this place A LOT but not all the time, it's just random nights. 

I am in this dark, creepy forest that is covered by plants and cliffs and vines.

 I see a lot of strange looking creatures, kind of demonic like but I don't fear them. I just get that creepy feeling. 

There are these 3 floating rocks in the forest.

 Near the floating rocks is this white mist of a person. 

His legs dissolved into nothing.... He talks to me all the time..

 And this dream is VERY vivid. And, it's the same dream every time I have it. 

I always talk to that mist. The strange thing is the dream is so VIVID but I can NEVER remember what he was talking to me about! 

GGGRRR!!!!

I feel like it's important and I need to know. 

Once day, though, I will remember what he said and I will definitely post what he says on here.
