Well, I had something very long a detailed typed out but my computer took a dump so I'll just say that that's all answered easily.
First of all, evidence is what makes the game. Without evidence all executions are random and no one would ever know who is bad and who is evil. No matter how much you may trust someone, without some sort of evidence, there's going to be the chance that someone might not believe you (that's the very short version).
As for the dreamers not being able to prove themselves, that's very unlikely. Unless the team that the dreamer is dreaming of is dead, the dreamer shouldn't have trouble proving themself. Even if the team they are dreaming of is dead, if they claim to be the dreamer and no one else has claimed to be it (which is actually very unlikely now that I think of it), it can easily be proven/disproven.
To the comment about knowing if a dreamer is telling the truth or not: Beyond what I already said about another person not claiming to be a dreamer, it is also unlikely that a person would fake being a dreamer if they thought there was a chance of that type of dreamer actually being in the game. The person can pretend to be a dreamer, but dreamers are usually know fairly early in the game and it would make it that much easier to peg a baddie just because they faked such an important role. Also, because of this, hardly anyone fakes being a dreamer because they can't just shout out that so-and-so is bad and then be wrong about it, they'd be executed on the spot. Because of this, when a person claims to be a dreamer (werewolf/mafia or other baddie "team" specifically), they are most likely telling the truth. Although if you are a far out OMT, you have more of a chance of faking that you're a baddie (as WIS did for example) and it being believed.
--------------------------
I cut out about 3/4 of the post, but in short:
Evidence is basically what structures how the game is played and without it, the whole thing would be done randomly.
Dreamers can usually and fairly easily prove their role, that's usually not a problem at all.
Baddies usually don't fake being a dreamer unless they are a one-man team, but even then it's not done very often.
--------------------------
Disregarding the evidence for a second, I should also mention that there are plenty of players that have been cleared and that it would probably be in a player's best interest to contact one of these people (heck, I know you have one yourself MJ

) They may not be mentione ddirectly on the thread, but they can probably be found hidden on the thread somewhere. If you tell someone that has been proven innocent, you're most likely to get your point across, otherwise, it may be up to interpretation (though sometimes people will take your word for it, but in the situation that there are still a ton of mafia members running around, we should be a bit more careful).
Yeah, that was still fairly long.
