Do you think that children experience a mental unawareness?

Yes, children can experience periods of mental unawareness, especially when they are very young. This is because their brains are still developing and they are not yet fully able to process and understand all of the information around them. Additionally, children have limited experiences and knowledge, so they may be oblivious to things that adults would find obvious.

As children grow and develop, their awareness and understanding of the world around them will also increase. This is due to the development of their cognitive abilities and their exposure to new experiences and knowledge. However, even as adults, we may still experience moments of mental unawareness or "zoning out" when we are distracted or not fully engaged in our surroundings.
