: "Sandy, have Clarissa the mighty open the left side of the box first."

: "Uh, no, I guess not, but I think she should also eckchay for apstray before opening the box."
: "Yeah, Clarissa checks for traps before opening the left side of the box."
: "Arrrrghh. Dave, get out of here and roll your next character—and put him about a million experience points in the hole, too!"
Is the DM going to allow communication between players whose characters are either dead or separated by a sound-stifling distance? The situation is bound to arise. The character who takes independent actions may try to pass on what he has learned to his compatriots to help them catch up (or, more likely, rescue him from some predicament) or the sole survivor of a party gets lots of help from his deceased buddies when he tries to solve the puzzle that stands between himself and freedom (and, coincidentally, the opportunity to resurrect their characters).
While some DMs may not care, after all the point is to have fun, others may find having their best trap foiled by a character acting on 'spirit voice' tips from a the corpse of a recent companion.
Each DM must decide this point for himself and if voices from beyond seem unfair to him, then he needs to say so and make a suitable punishment for the crime (one that affects all parties concerned).
