i try to go back home when I was a kid, it's hard to get back, but when i finally reach it the door is closed
This dream may represent feelings of nostalgia and a longing to return to simpler times or memories from childhood. The difficulty in getting back home could symbolize the obstacles and challenges you may be experiencing in your current life as you try to reclaim a sense of security or comfort from the past. The closed door can symbolize feelings of disappointment, or the idea that the past can never truly be revisited in the same way. Alternatively, it could represent a fear of being unable to recapture the innocence and simplicity of childhood.
