Low frequency, highway white noise, metal towers being hit or something in distance. It can be so loud. It�s a consistent noise all night. Its driving me crazy. It�s starting to drive me nuts. I want to at least know what it is and maybe it would help put me at ease. But, if it starts to get any louder than it has been tonight, I might go freakin crazy!!! Seriously. I can�t sleep.

the accounts read alike, found by meaning rather than by shared details
Write it down while you still remember the details. We will look for the others.
Tell us what you sawIf this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
Nothing is tracked back to you and nothing is sent on your behalf. The link is just the page you are reading.
