Hola Anxhelino1234.
I too have repeated dreams of the same places, sometimes with different characters in them and sometimes changed versions of the same ones.
I have some ideas of what may be going on, if you want to 'hear' my interpretation:
i dont know what it means or what its suppose to mean, but every time i get it, i get this very odd feeling, i am not scared, happy, sad or anything.
-Recognition?
I just stand there staring at a street filled with people,
- Is it a street that is familiar, like where you grew up, or is it strange? If familiar, it could symbolize your life, your mind, or even your body, but if it's unfamiliar it could mean something else altogether.
Depending on the familiarity of the place, the people could be aspects of yourself, or ideas or thoughts.
as soon as i blink theyre gone,
- I'm thinking that this has something to do with beliefs or fears. If looking at them and blinking makes them disappear, it seems to me that they could mean fears that turn out to be unfounded the second you face them, showing how 'unreal' they were.
Or, if they are fears or beliefs they could be hidden from sight, stuff you don't even think or realize you have.
first time i had it it was night time (in the dream), second time very hot sunny day and previous time it was snowing and all three times the exact same people (basically doing the same thing). Also this is the first time i can remember every specific detailin that dream e.g.: road, houses, shops, weather, people in it...
Depending on who the people are and what they are doing may give you some insight.
