The music thing
Music has been found to play an important role with most empaths. In a way it can be medicine for our souls. In fact, when I am at work having a tough stress day, I use soft music to calm and ground. I have also found that as my empathy has become stronger over the years that I struggle with certain noises that didn't used to bother me. Sounds from a blender or my teenager playing loud rap music is like nails down a chalk board for me.
I wonder if you had a similar reaction to music being playing differently and at a faster pace. We empaths are known as being over-sensitive compared to others. You may have sensed a different vibration from the music that just annoyed you.
I have joked to my husband that maybe my hearing is just super sensitive. Unfortunately his is on the other end of the spectrum.
Oh goodness... that really sounds like a dark time (I'm super sensitive to music, too.... Sometimes even songs that I like annoy me if I think about them in certain ways..)
