High School or College?

This one is spotty, but I remember a good portion I think. I was living with my mom in an apartment that slightly resembled the actual apartment I used to live in with her. I had some friends over, and it was nearly the last day of school, but I hadn't been able to attend because I was out giving birth to my son (who I actually gave birth to nearly four years AFTER high school.). We were sitting in the bathroom and my friends were updating me on everything that was going on at school, and telling me that our teacher, who I guess was named Ms. Tish, had finally let the class finish a movie we started forever ago. Throughout these discussions, I found myself remembering a high school, and I had to keep correcting myself that I was in college. We were discussing whether or not I should even bother going back to school this year as there were only three days left and there was no way I could pass the final exams. Plus students weren't required to attend the last few days if they didn't have an exam. My friends left I guess, and I proceeded to straighten my hair with a broken straightener. I remember someone telling me I was ugly and no amount of straightening was going to fix that, or something along those lines. After straightening my hair, I took it in the shower for some reason. After I got in and turned on the water, my mom came in and demanded to know what I was doing and why. When I told her I was taking a shower, she said "uh huh, sure." or "yeah right.", which is weird and very uncharacteristic of my mother. She was never the type of person to call you out on your lies whether you were lying or not.
I remember another part of the dream involving some friends of mine, but I don't remember exactly what point it took place at. We were out in what I guess was a swamp as there was murky greenish water and several unsafe bridges over it. Me and two other guys (I think Jimmy and my last ex), were riding motorcycles (which I don't even really know how to do) over the bridges, and someone ended up crashing or sinking or something. Otherwise we had fun.
