Sharke the scarier thing is what if someone really is yelling at us lol.
Being a study in the paranormal ( but not believeing everything I read or hear) I have run across several ....well quite a few instances of sound reproduced in a way that it isn't sound as we know it . Go figure that one. A good example is a family in a haunted house who hear footsteps in the attic . They go to check it out and there are no people walking around up there. Knocks coming from the ceiling but there are no people knocking. I think this is some kind of simulated sound that we perceive as auditory but it is somehow manufactured. Sometimes only one person hears the sound when there are others present. In that case something bypassed the ears and went directly into the auditory canal. Aside from crazy people and drug users this is something that has happened repeatedly to many people, especially in haunted settings. Of course we can dream sounds or recall sounds and hear them "in our heads". I'm no expert in this stuff but I know it happens.
