Often that is a 'Call' for you to be attentive - not to ignore..
There is a Spirit saying...I have used many times - "Silence doth toil it's Bell - and calls the Dead to awaken, but Deathe hears nothing - for their sleep will never be broken"...
You never mentioned the 'words' spoken - which may have been a help - nor have you mentioned the Times that this occurred - other than every other month.

I do have tinnitus, but I've also experienced the ringing you've experienced. It is a different tone than tinnitus. The fear for my life and paralysis did not accompany the tone. We are probably experiencing different phenomena.
I have! Basically I have those experiences a lot- I am a psychic and sometimes I have to go throught this weird ritual where I calm down or review like a dozen entities that I have contacted to kind of put them to sleep like babies. They are really retarded and generally cant get their shit together. They say its because I don't have a perfect life- I am a struggling adult college student without a license:( I know where you are coming from.
