Dreams happen when parts of your brain works even when you’re asleep. Everything you dream is generated by your brain and don’t have any connections with outside reality, though the content may or may not be influenced by your experiences during the day.
Nevertheless, dreams can be incredibly powerful because the emotional parts of your brain can become activated. These emotions can often continue well past your sleep because many emotions are just chemicals released into your brain, altering its functions. If you dream that your spouse cheats on you in a dream, you may really feel that she has, even after you`ve woken up and understood rationally that she hadn`t.
Because of this, it`s understandable for many to consider dreams as important portals into their lives or even the future.
