Extracting old information, memories while lucid?

There is something I desperately need to recall. Someone's last name and a couple of other things. I know I've heard it, so theoretically it must be somewhere in my subconscious. I remember the consequenses in which I got the information, remember other parts of dialog.

How can I get to this information in a lucid dream? I'm sure it's possible, everyone had this situation when something that you forgot comes to mind out of the blue, right? I think it's somewhat similar.

I was thinking about "asking" for recreation of the scene as a movie or asking a DC about the info, but once I'm lucid everything is really dependant on me and DC may lie and the scene may be wrong...

Guys, please tell me if you had any experiences with this or just share your thoughts on topic, I really need this.

I can't remember a situation like that but I'm sure that it's possible cuz everything you've ever heard is in your subconscious mind. Maybe you can try to go to a place that reminds you of the thing you want to know or for example if you can't remember someones last name, just carry this person into your lucid dream and ask him or her "What's your last name?" . I don't know if it'll work, but I think it's interesting to try..

Thank you, I guess, I'll just keep trying, asking the person, recreating the situation. Hopefully I'll get what I need :)
