Dimension X

Ok this is probably one of the longest dreams I've ever had... So all I remember is that I was in this parking lot, and there were a few people around me and I had a cell phone in my hand, which is weird because I don't actually have one. Then I was in a convenience store looking for something. I remember at some point in the dream I had randomly gotten $40. So I was looking for something to buy I guess. Then I remember the convenience store somehow turning into a full-blown grocery store. So I went further inside and I remember the things I got. I bought only 2 things, or at least 2 that I remember. A box of Chips Ahoy chocolate chip cookies, and a can of Chef Boyardee ravioli. Apparently it was the last can of ravioli too... The inside of the store itself was bright white and the shelves were shorter than regular ones. So I was taller than them. Some of the items were open, and their contents spilled, too. That's all I remember... It was probably one of the longest dreams I've had, but what I find weird is that I was only semi-lucid. I knew I was in the dream, but I still went along with the "story".
I've had quite a lot of dreams where I'm in a store or somewhere public. And in all those dreams, it appears as though the main focus is always to get home. O_o
