Actually, no. Just laying down on the trampoline, and looking into the blue sky, as Pkmays mentioned. Actually, that article in Wiki is probably what I'm seeing. However, I don't think it's Tinnitis that I'm hearing. By extra, I mean hearing voices, like people talking, and sometimes music. When I was younger, I would be scared, but as time went on, I just got used to it. I think maybe because I've accepted that it may be radio frequencies or something. But through a pillow? I still don't get that part...
