HJ, Did you hear a voice recently?.. For me these things usually happen in cycles.
A few times in the past couple of years I'll get home, (Have a 2nd floor walkup apt) & I swear I hear indistinct voices while walking up the stairs,
No TV's on, Neighbors not home, Our walls are thick.. It goes away once I concentrate on it.
A few weeks ago I was heading out one evening, was turning out a lamp & distinctly heard "..OUT" as if the GET in "GET OUT" was covered up by the sound of the lamp turn switch. I was headed out to my 2nd job at the time.. That threw me for a loop.
It's ALWAYS when I'm not thinking "deep" but am totally in the moment, as if there's an alignment involved in order to be receptive to whatever the heck it is?..
