This took place about 6 years ago when I lived with my mom and stepfather. We stayed in two story house and my bedroom was downstairs while the other bedrooms, living room, and kitchen were all upstairs. The backyard bordered a canyon and there was a lot of trees and brush.
When this particular incident took place it was about 10pm on a Friday night and two friends and I were in my bedroom getting ready to go out to a club. We had not been drinking or anything of the such. My parents had already gone to bed but I heard voices upstairs as we were getting ready to leave so I went up to check. My stepfather was comforting my mother and she looked terrified. They said that she woke up with the worst feeling of dread and sadness that she'd ever felt as if something terrible had or was about to happen. My mother has never been one to make things up and she could not have faked the horrible look in her eyes.
We decided to look around outback when my mother said she felt like something or someone was there. By this time my friends (Craig and Israel) had come up to see what was going on. We got a flashlight and one of those big spotlight flashlights and scanned the backyard for any sign of animals, people, or anything else. We did this from behind the closed sliding glass door since we didn't really know what was out there. We didn't see anything and it was a clear night so Craig, Israel and I went out to the back porch and looked some more. I had the large spotlight and I looked through the bushes and the porch itself and even straight up to the sky thinking I might see birds or something. Nothing.
We concurred that there was nothing there and then it started drizzling rain. I remember saying "that figures" but then it occurred to me that it was a clear night. I looked up at the sky again but didn't see any drops. I started to get nervous and used the spotlight to look up but there was no rain coming down, yet I felt it pattering on my face and arms. I looked very carefully but could only feel the rain. I asked Israel "do you see that" never mentioning rain and he looked for a few seconds then his eyes got real big and he said "there's no rain!" He clearly felt it too. We ran inside the house immediately and locked the door. We both confirmed that we'd experienced the same thing and decided to not investigate any further outside.
We never could find any explanation for the occurrence as there weren't any sprinklers within reach of where we were at. The sky was clear and even if there were, we couldn't see the drops with flashlights.
