Try not dreaming for a while. That really fucks with you.



One of the ways in which I think humanity can achieve immortality is to utilize dreams to create a world where we can live in our dreams. I've had dreams where time passed noticeably faster or slower than the actual time I was awake, so our perception of the passage of time is definitely variable in dreams. It seems feasible that one could somehow live in a dream for 1000+ years during what would normally be considered a human lifetime (~80 years). At that point, assuming that our bodies are not in danger and are up kept as necessary, we are effectively immortal compared to a normal human. It might even be possible to significantly lower the body temperature or something else to preserve the body beyond the normal human lifespan, assuming we don't need to utilize it anymore and it serves only to hold our minds.
