Possibilities?

Is it possible to find the answer to things that havent been explained yet?

I ask this after the apparet answer to how a platypus (mammal) can lay eggs....

I think it's possible. But only, if you already have all the info in your head, you just didn't put 2 and 2 together yet. And you are actively looking for an answer, thinking about it a lot.

That's how the Periodic table was "invented". Russian chemist Mendeleyev already knew all the elements, their atomic weights and other characteristics. And then, in a dream, he saw a table with elements organized as they are now. And this is just one example.

My Dad once had a vivid lucid dream where he was back home in the island of the Azores, where he was born and raised. He said he was walking around his parents farm and he went inside their tool-shed, and saw my grandfathers black hat. My grandfather had passed away years ago before the dream. When my Dad woke up, he called my aunt back home in the Azores and asked her to check the shed to see if it was there, and it was. It's really interesting too because the last time my Dad was in the Azores was in the 80's, and nobody had seen the hat till my Dad had that dream.

It might have been coincidence, but it's truly amazing that a dream can bring up things like that. I believe dreams can give us answers, and guide us with our problems. They might not solve them, but they will give you the information necessary to do so. Like gab said, If you're looking for an answer to a question that you know how to solve, it's possible.

Who really knows what is possible in dreams? Some (often called "sceptics") think that dreams are merely the brains operations, and whatever knowledge appears in dreams is already logged in the brain - or at least arises from what is contained within it.

Others (going by many different names) think that dreams are a portal to other aspects of the complete universe, than we can reach through "normal" physical means. From their perspective, there should be access to absolutely all knowledge - whether already present in the brain or not.

Einstein reportedly got the idea for relativity theory through a dream, in which he was riding on a light particle (photon) sent out from the sun. Was this knowledge already inside his brain, or did he tap into "the collective unconscious"? Your guess is as good as mine.
