Nauseation

Last night I had what I would consider a successful dream. The dream started off in a city I used to live in a few years ago, I was in a blue hatchback style car as we drove through the park. the car was moving towards the west of the park, and I remember actually choosing how I was going to wave to the group of people sitting at the benches. (which is very exciting) I must have been thirsty because subconsciously I kept making drinks appear. First the destination of the car was over to grandstands that I somehow knew had a blue jug of kool aide there, but before I made it much farther I decided to walk. I started walking towards a wooded area, not far from the bench the people I waved to were at. I stopped at a water fountain and took a drink, and it had the most awful chemical/metal taste to it. I spit it out, and continued walking up into the wooded path. I soon met a dog on the path, it had barked a couple times which made me skeptical of petting it, but I did anyhow. I remember backing away from the dog a few times, not really sure what its intentions might be, but everything was fine and I carried on. As I moved on, I started meeting up with people I know in life, and we started to travel in a group. I think I may have been in the realm of my dreams where every dream I have ever had was interconnected like some sort of dream world, it was amazing... I visited many places I had dreams of, and they weren't far apart at all. I guess I never knew they were so close, because I never had the notion to explore my own dreams? I'm new to the concept of actually taking control of your dream, I mean I have always had dreams with a degree of control and choice, but this is a new level for me. I woke up so excited and ready to tell everyone what had just happened!
