Low hum, like an electrical transformer, very strong but low frequency. Sometimes notice a pulse with it that I can feel the pressure on my ear drums. I generally do not feel well living in this apartment. When I leave I begin to feel "normal" again - more energized, more clear thinking. When I return to apartment I feel the "malaise" again within 15 minutes.

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.
