What are meanings of some dreams?

It should be fine. I have weird dreams all the time. Dreams are just whatever you're thinking about all mixed together. It's sort of like a cake. You've got the flour (or in this case your dog), eggs (your mom), chocolate chips (your cousin), all mixed together, and your brain takes all this information, and turns it into a story. I completely understand how you feel. Once I had a dream that my sister died because a truck hit her, and she died in my dream, and when I woke up I was crying and thought she was dead for real. But she wasn't.
