I'm pretty curious as to how powerful your brain really is in a lucid dream. For instance, i know that the Brain can replicate pretty much any senses that you have actually felt in real life in a dream... But what about those that you haven't. Can the brain gather enough info about a feeling or an action to make it actually seem real?

For instance, Everyones been burnt before- but can your brain re create that feeling in the form of a fireball?

Or What does lucid sex feel like if one is still a virgin?

Does flying in a dream feel as though it would in real life?

I hope that this question makes sense... I'm not an experienced enough lucid dreamer to be able to answer these questions but I'm hoping that some of you are.
