In alpha and beta versions of Minecraft (prior to Minecraft's 1.0 release), if you attempt to go to sleep in an 'unsafe' area, there is a chance you will be woken up by an enemy mob.

If you sleep in a bed which is unsafe according to the game's rules but does not actually have an ordinary path to a dark area, is it ever possible to be woken up by a creeper, with the attendant risk of damage to structures?

I ask because I have slept in a somewhat-unsafe bed many times, and only ever met a zombie or skeleton, but never a creeper or spider, and I want to know whether I've just been lucky so far.

    Note: This question is obsolete as of Minecraft 1.0.0; if you succeed in going to sleep, you will get a full night's sleep.

The 'wake up' mechanic was removed in Minecraft Release 1.0.
This answer is only relevant for versions of Minecraft built prior to that revision, accessible using the Minecraft Launcher's Time Machine functionality.

No, a creeper can not wake you up/be a nightmare.

The results would be catastrophic and are therefore disallowed just like a creeper mob spawner does not exist for the same reason.

bugi74 has done some great research on the code itself which verifies this:

On each try it will roll a random monster type from the subset of skeleton, spider or zombie

  • Good point! If monster spawners exclude creepers, then it makes more sense that beds might too.

    but hacked in mob spawners spawn pigs, so do hacked in beds cause pig nightmares?

    Hrm... Then would hacked in beds in the nether produce dreams of cooked bacon? Jun 6, 2011 at 19:19
  • A creeper spawner wouldn't actually last long enough to make much difference. ;) Jun 6, 2011 at 21:52

"Unsafe according to the game's rules but does not actually have an ordinary path to a dark area" seem mutually exclusive. If a hostile mob can get within 2 blocks of the bed (even through walls) there is the possibility of being woken up.

I have seen numerous posts on the minecraft forums referencing being woken up by a creeper/spider but bugi74's interpretation of the source code suggests that creepers cannot spawn.

  • It is completely safe to stand next to the bottom right bed forever. It is not safe to sleep on it because of a bug in Minecraft. I am talking about the mobs Minecraft teleports into your house-with-an-unsafe-bed when you sleep: can they ever be a creeper?

    @OrigamiRobot: Have you personally seen a creeper appearing next to your unsafe bed?

    I've never ever woken up to a creeper. Obviously the consequences of that would be far worse than any other mob, so maybe it is specifically disallowed.

    @OrigamiRobot - Has the question changed since this answer was posted? I find this does not answer the question as it is currently worded.
