Yes, I’ve met Adriana Lima before. Well, if you mean in waking life then my answer would be different. To be more exact, I have met her as a dream character in one of my many dreams. Although the experience of meeting her was probably different to what would occur in reality, dream characters can give the dreamer a very real experience.
A dream character (or DC) is any character you encounter in a dream, whether it be a lucid or non-lucid dream. Dream characters will usually be human but sometimes will take the form of animals, robots, or even the abstract.
Typical dream characters will be people you know (e.g. friends, family, peers) or celebrities. The occurrences 0f such dream characters often coincides with the level of contact in waking life. So, a friend you recently spent time with may likely be encountered in a dream or an actor from a movie you recently saw will make a guest appearance in one of your dreams.
However, this is not always the case. Some dream characters are exclusive to the dream world. Often times these unknown dream characters will only serve the roles of “extras” and will be based on stereotypes held by you. For example, imagine a dream where you find yourself lost in a foreign country you’ve never been to. You don’t necessarily know how the people look or even the language they speak but your mind has some preexisting stereotypes and will fill in the rest.
An unknown dream character may also take the role of a dream guide. The dream guide does exactly that, he or she guides you through the dream landscape. This is often a recurring dream character who may give you clues and assist you to achieve whatever your goal may be in the dream. Not everyone meets dream guides in their dreams, but you may be able to summon one at will once you are experienced with lucid dreaming.

Its interesting stuff how dream characters come about. I’ve never been to Paris and have no idea what the people there are like. One night I’d a dream I was wandering around the city and the only person I conversed with was a Mexican gangster looking guy with no top on, covered in tattoos. Only after I woke up I realized that its probably very unlikely Parisiens look like that haha.
Haha, great anecdote. I too have had some similar experiences. I find that the mind is quite good in filling in details but it gets carried away at time, especially when non-lucid.
