So I'm playing small tribes solo and while running around on my Ravager, I heard a sort of singing or more like humming. I know that the huge crystals make a hum but I'm right at the edge of Green and blue and I hear a female survivor singing/humming. It's not the only strange noise I've heard, I also heard voices talking to each other, very distant though like an echo. The final noise I've heard was by portal lake, I stopped by to fill my Water Jar and heard drowning. Not like another player in the area, but very distant like an echo. My friend says he has heard other noises like hungry survivor noises and other stuff but he said he has never heard these specific noises. I'm pretty freaked out and want to know if these are actual noises in Aberration, or if I need to clean my ears.
