What is the meaning in a dream of chemistry

I dreamed of exactly what I've experienced for decades. I saw myself living life as I exactly would and have in the future, and that future is now. The Future was the past, the past was the future, and the present is both the past and the future at the same time reoccurring in reality. Was it truly a dream? I was asleep. But unlike normal dreams, I could taste, smell and even hear the thoughts, feel the chemistry changes in my brain and feel the emotions I would have in the future. I have the same spouse and children now as I saw I would. That took over 20 years to come to fruition. I even saw the dreams I would have in the future, therefore I was having dreams within my dreams. And now I'm reliving all of it.

I'm taking a chemistry class and I sit next to a male classmate. As the lecture goes on, the classmate starts to touch and rub me in a sexual manner over my clothes underneath the table. The instructor catches this and we are both sent to a counselor to discuss this.

I have eleven brothers. At IHOP with two of them as we are leaving my brother Matthias tells me he hasn't slept for six days because its finals week and he is a double major in biochemistry and chemical engineering. I take the keys to our station wagon and then there is a guy with a gun and he wants my purse but I tell him I need to get my grandfather's diary but it's not a diary. It's my own gun and when the guy in the hood sees it he passes out and then I hear a huge thud and Matthias has had a seizure from not sleeping.
