Thank you for your comments!

I have been thinking about the whole thing and I am going to use a mixture of all you said.

So I realized, there are two themes going on:
1. A person accuses me. And I feel guilt.
2. An animal sees me and becomes violent. People say animals see people's soul so if an animal dislikes you, it's because you're a bad person, thus I am a bad person.

Both involve me feeling guilt/self-doubt. This is a waking life problem (not a huge one, but one nonetheless). I always worry too much about what I might have done wrong that could have irritated or displeased or angered others. But I let this affect me too much. Whatever happened happened. I can think of something to improve. Once that's done, that's all I can do. Maybe I can give comfort to the person but if they don't want it, then, I've done my best. I need to move on and remember I am a good person. This is a weird situation to me because it feels rude. The way I am going to deal with this is that I will spare a few seconds to feel compassion/empathy for the other person, seeing the "harm" that was caused to them (if any) without blaming myself. And then, I'll do the rest.

For the animal part, it's just not true that animals know if people are good or not.

Here is how I will react in a dream two both situations:

1. I will say "It's done. I am a good person. I can make mistakes." (to myself)
"What can I do to amend my wrongs?" (to DC)
if the answer is constructive, I'll amend my wrongs, if not, I'll say to myself: "I am a good person. Move on"
Then, I will look away and move on with my dream. I think it's okay to just think about something else once you've done everything and the other person is just creating their own problem.

2. I will say "I am a good person, you just need to know me better" (to the animal, then I can let it smell me)
If they are receptive, I will pet it and then continue my dream, with the animal or without. If the animal continues to be menacing, I will just look away and move on. I have faced the situation. I need do no more. Spending any more time would be a mistake on my part.

Conclusion: Like Oneup said, I think this must be my "expectation" causing all of this in the sense that I have a tendency for self-doubt. I have done a few things with consequences in my life, but none of them were consequences of me being a bad person, just mistakes. And any reasonable person would forgive me for them. So, I should feel sympathy for the person, and feel respect/awe for the way we all have effects on eachother, comfort the person if I can, and move on, never blaming myself. By blaming myself, I mean thinking "I am a bad person." I can think "I should of been careful about that." in a way that is compatible with "I am a good person" and that's good.

My answer also includes dolphin's because I do give the DC/animal whatever they want (to know me better or my apology)

Thank you FryingMan. I won't use your technique in this case because I think since this is recurring, it is something that needs to be dealt with in waking life and accordingly in the dream. But it's an interesting technique in a non-recurring scenario I might use when I've resolved this!
