Those aren't theories, those are the baseless conjectures of people who don't know what's what.
Dreams aren't anything special or supernatural, and they definitely can't effect the physical world. Every child has to learn this easily observable truth when they wake up terrified from their nightmares. And people such as myself, who maintain a high level of nightmares into adulthood, have to be even more aware of it. I've woken up before believing that I've had life altering crises to deal with many a time, only to have my rational mind kick in and realize it was all a dream.
So yes, dreams have to be disregarded as the nonsensical products of a partially shutdown mind. They have no mystical significance and anybody who tries to convince you that they do is most likely either trying to scam you or mentally ill.
For the most part I agree, but The Grand Nitpicker that speaks to me in my dreams demands I read some posts and nitpick at them
Anyway: Silly New Age Hippies are Silly. Yay for tautologies. Dreams, much like the rest of your mind, are products of 100% physical processes (funny, now that I think of it - it's much easier to accept things like dreams or mood disorders or hallucinations are caused by chemical reactions in your brain, but it's much harder to convince someone that the 'you' that reads this is, as well). So yeah, I agree.
What I disagree is:
a) Dreams affecting reality. Sure, what happens in a dream, stays in a dream. But what most people refer to as 'having' a dream is actually remembering a dream. And this way, dreams may affect reality indirectly. In fact, there is a medical hypothesis that night terrors (distinct from nightmares - nightmare is a bad dream, during REM phase, night terror is pure, irrational, abstract fear during NREM phase) may have caused a number of unexplained deaths in sleep, especially since people who died that way generally had minor heart abnormalities.
And, crossing over into b), you should
NOT disregard dreams. I find dreams, regular ones, not nightmares, equal parts fascinating and utterly terrifying, because they reveal what sort of mind lurks just beneath the threshold of consciousness.
I'm going to be rather vague, but I'll just say that: ideas are like vengeful ghosts. If you let one inside your mind and don't satisfy it (for whatever reason), the only thing you can do is to drop it from the stairs and into the unconscious, but it can and WILL, if it got implanted hard enough, haunt you in your dreams. So, to return to being a bit more plain language, dreams reflect ideas you don't want to surface.
I don't believe in true love and soulmates because that would be horribly depressing.
I just believe that if two people want to get together, they should be able to be friends without any romance. They don't have to have just friends for a while, but if all they have going for them is "You're my soulmate!", that's not a stable relationship.
First part I agree with, the second is a bit confusing, I am not sure if you mean what I think you mean.
Are you trying to say that a romantic relationship is kinda like an upgrade of a friendship? So, if you want to have a romantic relationship with someone, you must have all the things that constitute a friendship plus that little bit that makes it into a romantic relationship?
