Guys, I just saw it. Well, actully I can't say it was it, well, here's the story:
Ok, so I was working on a city build, by myself, I oped up the brick menu, then it appered
IN MY FACE! I wasn't that scared, though. I realized a second later that it might have been just a temp brick. But when I looked at my paint can,
IT WASN'T RED!!! Now I realized 2 things wrong: It was Cristmas eve, and I was on
BEDROOM LIGHT! So long story short, I might not play blockland for a while.
EDIT: sorry guys, false alarm. It WAS the temp brick, the paint can was on one of the effects, it changes to a random color.
Here's a cookie for all the troble.
EDIT 2: actully, it was the BRICKS emote. -_-
