UFO Sighting in Folsom, California on April 16th 2013 – Came out of cloud while i drove uner it then cut over trees out of site.

I was in the passenger seat driving with my mom on Folsom auburn road. I noticed a stranger cloud we where heading towards and I had the feeling I needed to watch the cloud. Just then the disc shape craft cam out of the front of the cloud. It was grey not smooth or shiny though. We where about to pass under the craft so I was leaning forward in my seat to watch it and it slowly cut over the top of some trees that where on the side of the road. It was out of site after that. Right after that I looked at my mom and she asked what was that and I said a ufo she laughed and thought I was joking. When I tried to tell her seriously she looked at me like I was on drugs or something. I tried to talk to a couple people about it but got similar looks. That's why I didn't report it till now. It's very upsetting that I couldn't talk to my family or anyone for fear of people thinking I'm insane or something. I just wanted to put it out there to see if anyone else may have seen it so I can have some reassurance. Thank you
