There was a humming noise vibrating through our house for 45 minutes and we now believe it could only have came from above.My wife woke me at 4:30 AM on January 14, 2003 and asked me what the noise was. I got up and checked the entire house including the basement and didn't find anything inside. My wife suggested I open the window and we found that the noise was coming from outside. I looked at my neighbors' houses and to my surprise because of the volume of the noise, their lights were off. I couldn't see anything (I never thought of looking up because quite frankly I never believed in such things) and went back to bed and told my wife that it must be someone's house alarm. I quickly ruled that out because the noise wasn't a loud screaming noise but a steady humming noise that did go up and down slightly. When I was going through the house the noise was just as loud in the basement as it was on the second floor, leading me to think it was vibrating through the house. I also had a very strange feeling as if I was being watched but I didn't have a clue why. Finally, at about 5:15 AM when we lay in bed listening, it suddenly got quieter and then forceful and seemed to drift away. We never thought it was a UFO (and we still aren't sure) until after we asked a few neighbors and found that they didn't hear anything. I kick myself for not looking up because right now I can't think of any place else it could have come from.((NUFORC Note: Many communities have reported such seemingly unexplained hums, including Monterey, CA; Taos, NM; and Seattle, WA. It is not known what causes the effect, but many have studied the phenomenon. The U. S. Navy, at one time, had an underground grid installed in Wisconsin, reportedly used for communicating withsubmerged submarines, using a very low-frequency ("long wave") electormagnetic transmission. The project was called "Project Sanguine," as I recall. That may explain the source of the hum reported by the witness, but that is a wild guess. PD)
