So im gonna try and just get the point and not try to explain every detail as it would be entirely too long as it already is. We live in the country and have our whole life's so not strangers or spooked by being in the sticks seeing and hearing things. But over the past 5-6 years in a old 1800-1890 road bed/ travel route a hundred yards or so behind the house we've been hearing whistling at dusk. And by whistling I mean a tune or a old song. And yes I've checked for actual people but come up with thin air. Doesent bother us as we've seen and heard some weird stuff we can't explain over the years. But this whistling is odd. We've normally always heard it by the roadbed either behind the house or 300+ yards down in the woods. But last year Me, my wife and a buddy all heard it crystal clear a whistle in the bedroom. This whistle was more of a "hey over whistle" and since then we've heard it 3 seperate times in the house at random times. Fast forward to just this last week I had headed to town when I get a call. It's my wife asking if I had left yet because she hears someone right outside the house whistling in her words "one of your stupid tunes" because I also whistle quite a bit just out of habit. Which I had already left but it only lasted for a minute or two and stopped as it normally does. Now this is where it gets even more weird is one of our family members live roughly 1/2-3/4 of a mile down who also have the same old road bed/travel route behind their place also says they hear the whistling quite a bit down in the woods towards our place. I'm not a big paranormal guy anyways as I've seen and heard alot of things I normally try to rule it out as something solid or rational but sometimes just can't with this being one. So does anyone know what it means or what it is? It normally seems to happen a hour or less before dark outside. Inside is random if any of that makes a difference.
