What I discovered that was probably paranormal tonight

I was standing on my porch and I couldn't see what was out there with the government night light and I could see that the light was lighting up the porch like it normally does and then I gets very dark for like 3 secs and there was no noise and then I looked at the night light to see if it wasn't working right and it was working right and there was nothing flying around it. It was scary because I am the only one up.
