For those who have the interested in it here is a few steps you can do...
First, visit haunted places. It doesn't have to be a frightening place which will close you down to the experience, but a location were many lives had crossed over, like an old battle field, a cemetery, or a known haunted hotel. There are plenty of books out there that detail these places throughout the United States, Europe and elsewhere.
Second, find a place where you can be very quiet and still. You are trying to open up that sixth sense which has been dormant for a very long time. We all have this capability, but like any muscle, it's become weak over time, maybe an entire life-time.
Third, start shutting out the thoughts in your mind that are racing about. You need an open receptacle (the quiet mind) to allow very soft utterings from beyond. You can't hear if you're too busy talking in your own mind (much like any conversation). The more you go into a meditative state, known as Alpha, the more you'll open up to hearing frequencies not normally heard.
Next, after you are quiet, calm, and clear, extend a request that a angel or any positive entity make itself be known to you. Then, just relax, wait and listen. If the situation is right, they will try and make themselves be heard in some way. And hearing is easier to attain than breaking through the physical dimension with actual matter, so expect that. It will probably be something short and perhaps blurted out, so don't expect a huge dialog, more like one or two words, or a hurried rush of whispering.
The few times I've heard voices, I was quiet and calm. Usually coming out of sleep, meditating, or spending time alone in a quiet and solitary state --
