dream fragment

Success!! I was able to recall not one, but two dreams, although the first one's a fragment.

Dream 1 (fragment)
I am walking down a hallway. and I see someone. But before I can tell who they are, my alarm goes off.

Dream 2:
I'm in a.... Duel? It's a YuGiOh duel. I ply my cards for a while, but as soon as i try to go lucid, the dream ends and I wake up, and my heart's pounding, from excitement or other emotions I can't tell.

Both of the dreams were surprisingly vivid. Also, I think these were triggered by video games, because the last game I was playing before I went to bed was YuGiOh GX tag force, and both of these dreams matched it. So could this be a dream trigger for me?

At least my recall's improving.
