They say it's not possible

So I watched these three girls walking down the street, no I'm not stalking them but they are beautiful girl none the less anyway as I was saying I was watching them, they were window shopping and laughing about what I don't know when something strange occurred to me. It seemed that as i was watching I was seeing more than three girls in fact it's very hard to explain, but I'll try as I looked at what one of them was looking at, it was a fine red dress looked very expensive but then I noticed as she looked away I was still looking at the dress but it was like she had put the dress on and now was modeling it for herself then I quickly looked back and she was looking in another window. now if that wasn't strange enough I started seeing the other girls doing the same thing, not with only dresses but with jewelery and makeup too, it was like no one was watching as they did this but every time I looked back at them they were walking down to the next shop. As I watch them for awhile not trying to be to obvious I also noticed that it started to happen faster sort of as the more I watched the more things they would be doing, I don't think the mind is made for what I'm about to say so you'll just have to think of it as a story, well here goes not only where they doing all these things at once it was happening in a blink of an eye and then something else would be happening and not just one Girl but all three where doing it. what bothered me more than anything was they didn't even look like they knew they where doing anything . I know it sounds strange well I had to stop it was like no matter where I looked at as the three of them pasted a store they were in side trying on and looking at everything but still walking and talking as they went down the street. I'm not a scientist but I believe I was seeing their subconscious moving in our world as their conscious mind did what they where doing by walking down the street. I don't know how this is possible since I believe the subconscious mind is working close to the speed of light which would make it impossible to see or are we actually able to see things moving faster or at the speed of light ? well guess I'll never know.
