Funny Dream While Napping

So I tried taking a nap a little before noon this Sunday morning (I almost never take naps) ,and, after a while of just lying in bed, I eventually fell asleep and had a short dream.

I think some stuff might have happened before this point, but this is the part I remember clearly:

I am sitting in a small restaurant, and suddenly a random girl is sitting next to me. I take notice that she actually looks like my (real life) girlfriend, except with a TON of makeup. Of course, I find her attractive. She begins to suggest in a subtle way that we... well, do some stuff... Eventually I cut her off, and say that I actually have a girlfriend, and while I think she is very pretty, I have to decline. Besides, I'm only 17. Suddenly, she is sitting across from me. As I finish saying this things, she begins to smile a bit. Then, I see that some of her makeup is dripping. The realization hits me that this has been my girlfriend the whole time. I laugh and push her as she begins laughing as well. Then my brother comes out of hiding, and my girlfriend says something like "I told you! I told you!" Apparently she was just testing me to see how I would handle the situation.

I wake up a few seconds after that. I know this post seems really random, but I was just so surprised that I could have a dream that vivid in such a short amount of time. Just felt like I should share this and be more active on this site.

In conclusion.... I might have to start taking more naps! :D
