When we hear a very strong intense sound [they say there’s no loud or low sound, but strong or weak] …it keeps echoing in our ears for a while.
It may even feel like hearing the sound again but we know it’s just the echo.
There are things we experience in life that are so intense that sometimes we can feel like experiencing that again.
But that moment has gone and a new moment has come and still the reality is sometimes confused with what is just an echo.
It will cease at some point. I still hear it though.
