Does anyone else hear a noise like something is cracking in your head as the cluster builds? Once it is full blown the cracking is gone. I'm thinking it must be pressure building in my head (things swelling and pushing on other things)??
It doesn't do it with all the clusters but maybe I'm still asleep when some of this happens Because I usually only hear the noise during the day time build up of clusters, which I have few of.
