A dream within a dream

Hi! Im new at this, so I hope Im in the right place.
I had a dream within a dream, and then almost a 3rd one before I woke up.
I was in the grocery store shopping and I remember I only had 25$ and I put a few things in my cart and then I was out in the desert at about dusk. I walked out aways from a small green building I was standing by & was excited to go exploring but had in mind that it was getting dark & that my family would expect me back. I didnt go far before I came upon a cast iron sign that appeared to be from the old west, with three faces each stacked one on top of the other. I sat down on a stool in front of the sign and a news paper blew up aginst me, I was really interested in what I found and wanted to bring something back from it so I ended up trying to get inprints of the sign by scribbling a pencil over the newspapper pressed up aginst it, but I was so tiard. As I scribbled I could see the impression of a map working through onto the paper, but Ikept leaning my head aginst the sign and closing my eyes. It was then that I felt myself start to fade into black when I said to myself " what the hell am I doing Ive gotta get back, its freggin dark, why cant I get this done! Then I woke back up in the store with a bunch of stuff I didnt put in my cart, in my cart and I asumed I was sleep walking in the store, trying to hurry up and put stuff back I couldent pay for, and I woke up in my bed at about dinner time from an exhausting nap.???????

Wow thats pretty cool, tell me if im right.

Truly in real life you were sleeping in your bed or taking a nap.

In your dream you were in the grocery store buying groceries.

Then you appeared all the sudden in the middle of the desert.

Then you closed your eyes (This is what I think made you go back to the store) You then thought to yourself I am supposed to be getting home. In doing this you went back to where you thought your reality was which was the grocery store.

And you could of woke up from getting to anxious or excited or nervous.

And then you woke up. Does that sound right?
