Dreaming and Hamlet's Most Famous Soliloquy

In Hamlet's most famous soliloquy where he talks about whether to live or not to live, he talks about how if one were to kill oneself that we would enter the afterlife, the unknown. He talks about death would be like a kind of sleep where we would dream; however, Hamlet mentions that these dreams could be bad dreams. I love how Shakespeare makes Hamlet tie in dreaming with the afterlife.  Dreaming is always something that has fascinated and that is really strange when you think about it. I think it's really interesting how Hamlet describes the afterlife as dreaming in a way because the afterlife and dreams are both ideas or concepts that are unknown. When you dream, you could have a good or a bad dream. The afterlife could go either way also. I read some research about dreaming online, and I found it interesting how dreaming is a phenomenon that is still very mysterious and bizarre that scientists do not have a complete explanation for. The question of why we dream is unanswered by scientists today; therefore, why we dream is a phenomenon that is unexplainable just as how Shakespeare portrays the afterlife as something unknown also. It amazes me how dreaming and the afterlife are still ideas that people this day deal with and don't have answers for just as people also experienced during the Elizabethan time.
