A dream from my childhood, what does it mean?

[Sasha]

When I was small, about 6-7 years old, there was a weird thing going on with my dreams. Every time, was it a bad or a good dream, on the end of it I would dream a mask. It was a black one with red stripes under the eyes, on the forehead and on the cheeks. The mask was on a wooden plate and place on the wall of an old shop (like an Indian shop). The room was dark so I didn't really see anything else, but there where some other things around the mask, like some old pictures and other old stuff. It happened every night for 2 years and than it stopped (all of a sudden, with no warning...I didn't even pray for it to stop). Sometimes, when I was aware that I was dreaming, I would say to myself: "Here it comes...now the mask is coming." and it really came. I could feel it...and the feeling was horrible. It looked really scary, like it was angry, and sometimes I could here a sound like it was coming from a horror film. I would wake up with a racing hear and all sweaty. It was a hard time for me. What could that mask mean? And why did it stop even thought it was coming to me every night? What if I dream it again? And is it possible to find that mask in really life, because I kinda have a feeling that the mask really exists
Thank you
