Why is that Dog Smoking?

I have been having very vivid and active dreams here lately. The problem is I can't remember them very well. I'm not sure why this has been happening lately, but I really wish I could remember more of this stuff.

Last night I dreamed I traveled on a jet ski to a Jerry Savelle service where I continually stood up and sat down in a different seat. The night before I dreamed that some guy I went to high school with (but barely know) stepped out of his car smoking a cig along with his 8 year old son. I mean my friend was actually holding this eight year old kid and the kid was smoking a cigarette. The dad stooped down and put down his cig on the ground and this dog came along and picked it up. The dog proceeded to come up on the porch where I was at and started puffing on the cigarette. I was like "What's going on here, dogs can't smoke."

These are just very small portions of my last two dreams, although by the way it sounds I'm a little relieved I can't remember the rest of them. I know this happens to everyone occasionally, but what's the cause for it happening so often? Really sleepy? Weird day? Subconscious with a sense of humor? What are your thoughts?
