okay, so here's the thing. at least my thing. no not that
i'm pretty certain that you really can't tell whether it's something bad, or not. or better: in my opinion you can't generalize it - everybody has to know/decide for himself or herself. (also it's depends on the situation)explanations via examples:case 1:
you dream of killing somebody or something for no comprehensible reason (or maybe because in that dream you even enjoy it).what i think about that:
i'd try to figure out where this idea came from.
like working on questions like: what is bugging me, that my subconscious decided to deal with it this way? there must be something that i'm afraid of (even when i did it for fun) - what is it?case 2:
it's a nightmare. something is threatening you or maybe something (or someone) you like.
finally you kill the enemy.what i think about that:
depending on how it feels i'd say that's definitely nothing to worry about, because to me thats a way of solving problems.
in waking life, when you manage to sort out a problem, you could metaphorically say you "killed" the problem.
i see dreams as the language of the subconsciousness - and it loves to talk in metaphors (you could say we're all poets). so killing something in a dream, can be like getting rid of something you're struggling with.bere aware
that putting somthing (or someone) to death, the problem does not have
to be solved. but if that killing was an act of supression, your subconscious will still find a way to express what it has to say.
so i don't think it can do you any significant psychological harm.
but afterall i think that killing DCs is almost always
a waste of time. why should you do it? why not decide not
to do it but instead work on that thought right inside that dream - it's a great opportunity to find out what's bugging you. don't forget: technically you're hanging out with your subconscious.
for example ask
the dream if there is anything bothering you and if, what it is. also (if there is something) you can straight forward ask the dream for some advice how to solve it in a healthy way. check this: http://www.world-of-lucid-dreaming.com/lucid-dream-self.html
once (when i was a kid and had no idea lucid dreaming had a name) i dreamt about something evil chasing me. i knew it would harm me, if it reached me.
while running i realized i was dreaming
so i instantly stoppped, turned around and yelled: "stop!". i angrily walked toward the demon-thing, telling it to finally calm down and stop scaring me. i was still afraid but that fear somehow pushed me and gave me the strength to stand up against it and acting like: "i'm the boss here, stop it!"
i can't remember everything but i somehow went to a semi-lucid state and the monster has turned into a teddybear. we were sitting next to each other, talking about what's going on.
i remember asking it something like: "why did you chase me before? why do you want to hurt me?" i also remember having tears in my eyes at that point. it felt like a very intimate and honest conversation with myself.
i'm 100% not sure what the teddy's responded but he told me that he's not trying to hurt me, but rather looking for help. when he said that, i suddenly felt his pain.
i hugged him and told him that everything is gonna be okay and that i'll hear him out.
back then, i didn't REALLY find out what the problem was but it was a very special dream which made me feel happy and more self-conscious for many days.
what i want to say is that i could have killed the demon but i'm glad i didn't decide to do it. i don't think it would have been THAT productive.
