You go to sleep, wake up within your dream world, and time travel from there.
I think this is inevitable in the future. We can talk about it for hours. How exciting this could be, how people would be able to live in their imaginary world, how they could travel places (even Mars), perhaps even meet God. How they could have sex with any person they want, how they can even kill someone....and so on. At the end this will become so addictive that people will prefer to live their fake lives in their dreams instead of going through reality where you have to deal with all kind of problems, where you can’t have sex with anyone... My point is, it will only isolate people even more and perhaps they eventually get confused about what is reality and what is their life in their dream. Did they really kill someone or was it just st a dream?...
It sounds exciting, but it’s also scary!
There are protective systems in us that would not allow it. If one tries to escape this reality and avoid facing its challenges, then at some point they would be blocked from remembering their dreams let alone operate within them.
In fact it's happening already. That's why people use drugs.
