irrational dreams

I talked to my mom last night, and she was very sad. Someone referred a guy to marry my sister, but he didn't like my sister, and my mom was sad. I chatted with my mom for more than three hours yesterday. I suggested her to expand her social activity. I don't know what can I do here for her. I am like a death who can't do anything in the other world. I didn't get any call from Lily yesterday, too. And it was so disappointing. I expected her to call me. I thought that she was interested, but it seems that she was not. She is living on-campus, and she has a class everyday, and there are many events this weekend in my university that we could go together, but she didn't call me. I wanted to go today to the cafe and meet her, but I don't know why didn't I do that.

I said that to say I had a bad dream last night. I saw my car had been stolen, and Ryan brought me to the school, and I was very unhappy because of that. I tried to call the insurance and police, but I couldn't because I was in the school to the night because I couldn't take any bus to my home. Then, I saw another dream. I saw my friend in San Diego had stolen a Camaro. Then we went to a shop to buy something, and he stole some medicine, and ran away. The shop owner noticed him, and ask me to give his contact information, but I didn't have. Then, I went out of the shop, and another guy chased me, and asked me to give his number. I said them, I didn't have it. They need to call the police. Then, I ran into a neighborhood called Pyramid that was like Egypt's pyramids inside to lose them, but they found me again. I said them, If I see him again, I ask him to give back all things that he stole.

I see bad dreams anytime I am unhappy. When I am happy, I see good dreams. Why is it so?
