Pictures using Camera have raining static effect

[ComDor82]

I did some looking around and I followed the steps using the 800 ISO along with some brightness modifications and so forth. It seems however when I take pictures, I notice this static rain effect. Is this normal of the camera? I also tried this on multiple lighting effects such as florescent and setting the correction to 50 and 60, with similar effects. I stopped useing auto however because I noticed a wave effect using that and that got anoying quick. Doing some research and seeing other peoples pictures, I do not notice that they have the raining static effect and wanted to see if anybody else receives this in mild light. here is a sample I took while getting a sampler at the local tavern.
