The Voice of Heaven

I've never been able to unzip the veil between this world and the world of Heaven. It seems to be, at least for me, closed with a lock on it. How about angels? Have you sensed that with angels? Either? Have you heard the voice of angels? Never anything supernatural in that sense or above what we experience each day. You probably have had the experience that you just have a terrible memory. Or maybe, like today, we had somebody that came in and helped us out. But we didn't pray beforehand. I don't remember.
