There are probably whisps of true memories, as they are included in your subconscious, but more than likely it would be representations of how your childhood affected you with abstract details linked with adolesence and all the time that has passed from then until now mixed together. Since you have grown since then I believe it would be unlikely to recover complete memories with no additional detail added by your mind into the dream. Same with me lately, that's why I'm up so late lol.
