Take the tour ×  Sometimes when I want to sleep within my house,
I can't because of the "You may not sleep now, there are
monsters nearby" warning. Within how many blocks does a hostile
mob have to be to my bed to trigger this warning?  share|improve

the full release — sleep is not allowed within 10 blocks of a
hostile mob.  Quoted from the minecraft wiki. Hope this helps.
