My spouse & I had just moved into an apt complex in Ontario, Oregon, a month prior & were sitting in our living room, reading. We're middle-aged, and interested in paranormal, but never thought something this bizarre would occur in such an nondescript spot.
The complex was set up with the 4 buildings facing the center where the fenced-in pool area was. It being winter, the pool was emptied as winters in Eastern Oregon are frigid at BEST, and brutally cold.
This was in late February-early March of 2012. The air was crisp and clear, the temperature around the 20s Fahrenheit. It was approximately 10pm, and we heard conversation outside. Paying no heed, we continued reading. But as time went by, it seemed more people were appearing to 'join in' the conversation. After 1/2 hr, it seemed a lively 'party' was taking place. We looked up, quizzically commenting on the oddity of the time and temperature, but soon returned to our books. After another 10-15 minutes, it grew exponentially louder & louder. It sounded as though 15-20 people were outside, talking and laughing and generally having a good time.
We sat there frowning at one-another until finally, my husband got up and walked to the door and stepped outside. Oddly, as soon as the door opened, all went deathly silent. He stepped out, and shut the door behind him to keep the warm air in and the frigid air out. He was gone for a few minutes, and walked back in with a look of incredulity on his face.
He thought maybe someone had been on a balcony and we'd heard the echoes, so he walked out to the fenced-in area of the pool, and looked all-around at the darkened apartments of our obviously sleeping neighbors. No people, no doors open, no light-on, even! It seemed that WE were the only people even awake at that time.
Was this a residual 'haunting'? A replay of a summer's evening from the past going through the motions of a time-gone-by? We never experienced this again, but I found it worthy of retelling here in this forum, and my hair tingles as I type...
