Our brain during sleep and problems solving

Sometimes when falling asleep while thinking about a problem, we wake up with a clear description of the solution.
During our sleep, our brain works unhindered by our fears, unburdened by our limitations and its powers and abilities get unleashed.
Our waking consciousness is heavily influenced by fear, doubt, and learned limitations. We filter possibilities through what we thing is possible for us.
Sleep bypasses our psychological gatekeepers. During sleep, our brain doesn't know that it can't solve a problem. It explores realms that our conscious mind would never consider.
This phenomenon reveals how our remarkable problem-solving capabilities emerge when freed from the constraints of our waking awareness.
The brain during sleep is able to link varied pieces of information in novel and creative ways that our conscious mind, with its tendency toward logical thinking, might never consider.
