Luckily, I documented it. The video didn't pick up much of it, but you can hear what is going on and our thoughts throughout the night. These occurrences happened over the course of several hours. It was quite strange. Even stranger- there is some weird light anomaly the whole time on the video while nothing showed up there while I was recording. I recorded on my phone (an LG Optimus L90) and have never had this happen before. Also, I actually had the video light on throughout some of it; while, at other times, the light was off- so that doesn't explain the light.
If you have ever had anything like this happen, please let me know. If you saw something strange that night, I would love to hear about it.
