They're your dreams So, Mr. Steiner, it's your imagination/unconscious coming up with the symbols and story that are most understandable by you.

I would start with the "easiest" and most fun: peanut butter to heal wounds? Did you have a lot of PB&J sandwiches as a kid and enjoy them? That's a healing of sorts? Good memories from when we were a kid?

Killing off dogs, then generic people, then yourself -- looks like some sort of progression to me but the Self gets saved? Have you been working on any psychological issues lately (like in the last 6 months :-) It could be you are making progress or it could be the opposite, the dogs didn't get your attention when everything was "going to the dogs" so you went on to killing people, "others" (ain't MY fault! I didn't do it!) and that didn't help so you graduated to killing yourself but Yourself wasn't having that

I would think up a dream while you are awake, same themes you think you see/understand with these dreams but with where you would like them to go? Let your self see you are working on understanding, you're trying to "get it" and would your unconscious please quite "giving it to" you in this fashion, if you please? LOL Talk to yourself, non-dreamer to dreamer.

You understand more than you think, after all, you weren't taken in by **** ice cream were you?!
