Not sure what your thoughts are, but I don't believe that dreams hold any real meaning. They occur when your brain is repairing synapses, and so pieces of information from your memory through your imagination or curiosity and even things from your senses (i.e, hearing a sound while you're asleep) can be randomly fired off and synthesized into a dream. So while recent thoughts or issues can creep into dreams, whatever happens in them has no bearing on what you may actually think/feel/believe while you're conscious.
Sometimes something fairly meaningless happens and we don't notice but it has a profound effect on our Psyche. Then again it may have been a momentary imbalance of thoughts in your dream. I for one am happy to know you want to stay here with us
I had a dream about carrying my own dead body. wtf, right? so i'm in the same boat with you on weird dreams. I believe dreams about suicide have to do with the intense need to change something. Something bothering you, that you would like to see made different?
