The first one, you're a cop, you imagine if you took a role like that there are too many things that are really strange that you have no control over.
In the castle, you were raised in a type of isolation, from truth, goodness, love and compassion. And if not a best fit, it is just an overheard conversation and there is no relevant comment. (again out of your control)
And why should we think the third part were different. A common dream is having to escape a monster and you can't run. Sounds like a wiener. Anxiety, fear, lack of control, lack of power to change the dream.
Because when you're older your subconscious is going to show you stuff, nothing like these, inspiring and noble dreams.
