I also have those hear tones happening a lot lately now and I do agree with FelineNostalgia (nice name by the way ^_^ ). I have read that it can be linked with angels trying to get your attention.
And lol about the ear wax
It could also be a medical issue as well which kind of concerned me personally, but I notice it happens coincidentally at times so I agree with you pinklady that it could very well be more to it.
I will be willing to share some stories
When I was doing my tarot on a certain question and I read the final answer, my ear started to ring. I nodded knowing that I am on the right path. I then made a pact with my spirit guides/angels to ring my ears to let me know if I am on the right track.
So one night I was with this guy and I was hesitant in kissing him as it was our third date. As I was thinking this, I heard the ring so I was like okay. LOL And I kissed him. It turned out that he did wanted to kiss me too and it worked out.
Another time was with my tarot and reading the cards, My ear rang to let me know I was reading the cards correctly.
Another time was the spookiest of them all. I was writing about sychroncities here at this forum about the messages my spirit guides were sending me. I was doubting the messages, but after realizing that the messages were real, I turned to my guides and thanked them and said that I believe in the message they were giving me. At that moment, I looked down at the clock (I don't know why, but I had an urge) and saw it was 1:11 and then at the moment, my ear started ringing. I knew I was on the right track *happy*
I hope these stories help you out.
