>>6 No, it's actually a pretty smart thing to do. If you put all your trust in memories that can easily be manipulated by dreams and subconscious ideas, then you're pretty stupid. That's where derpy situations come up. You say, "I remember [xxxx]!" Everyone else says, "But THAT DIDN'T HAPPEN!" You, "BUT I REMEMBER IT." Them, "THAT DOESN'T MEAN IT HAPPENED." You, "I REMEMBER IT, SO IT MUST HAVE HAPPENED!!!" Them, "=_= goddamn, man."
And yeah, I used to do that a lot.
Also, IMO, you can't trust anybody anyway :I But that's completely different than not trusting memories. If you write things down, then there is no doubt about the smaller details of events; but blindly trusting that your finer memories are fact usually isn't a good idea.
