Dimension X

This was strange indeed. My parents were gone from our house and I remember I was trying to get into some kind of safe in their room. Except it looked like it had a normal dial combination padlock. Ironically, my parents have a locked closet in real life that they hide all the delicious snacks in, and I totally know the combination. (Shh, don't tell them.) But either way, it was the exact same combination in the dream. 17-47-11

How did I remember it in the dream? That's what really confused me. It could have been anything else, but it was the right combination.

I eventually got into the safe, but my parents came home and I had to close the lock and go out into the kitchen.

Things were different now. The power was out, and the house was very cold. There was even snow in the house. I remember opening the door to the stairs and seeing the snow sloping off the stairs, like it had fallen there somehow.

I went upstairs to turn our air conditioner into "heat mode" somehow. But of course, it's an air conditioner, so there's no such thing as that mode. It got warmer, but then it got cold again.

My parents left once more, and I was able to get in the safe and get cookies.

Also, they were really delicious.

Dream food is great.

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
