Black mold on drywall where my bed is, how dangerous is it, help plz 10 points!?

Clean it asap, it will just keep spreading, mold is a living organism. Bleach will not kill mold, the mold will just "run away" from the bleach. You must use some form of disinfectant to actually kill the mold. Also check to see if water is getting in to that area from the outside, which is highly likely....good luck.
