I have had strange dreams as of late.
1. A sword that is also a key to heaven.
2. mention of saint peter.
3. I fight a demon, description: Hair black as night, Eyes darer than the darkest abyss, razor sharp pointed teeth, skin resembled lead. it said why fight something that is a part of you.
3. I battle "the" leviathan in chicago illinois, destroying it with white flames after transforming into: white hair, strang armor/clothing. and protecting 2 twin children form the leviathan.
4. a blade of serpent or dragon design binds itself to one of my wrist with a metallic wrist band and unseeable chain, sword: mostly metallic green. then after binding to me in my head i hear the name Muramasa.
5. a red handle dagger thats blade burns hotter than hell and changes into sword.
6. dream mentions something about fusing with my inner angel to become an angelic like warrior and i do.
uhmm demons do not have "Hair black as night, Eyes darer than the darkest abyss, razor sharp pointed teeth, skin resembled lead" not to be rude or anything :P
and it was probably just one of those weird dreams
To be honest, this does seem more like the influence of mingled pop culture with whimsical fantasy. Dreams will often appear like this without any true depth of deep meaning.
Seems more likely that you're feeling troubled, like the world is awry (this does not mean the whole world is awry, only that you feel as though it is), or you're otherwise going through some troubles. Your subconscious builds you up, showing you that you can take down whatever troubles come your way.
Muramasa is the name of a famous Japanese swordsmith. Interestingly, the Japanese had very little to do with Christianity, angels, etc. Muramasa lived somewhere in the 14th-16th centuries... well before Christianity was even known to the Japanese. Again, likely a blend of pop culture, historical reading, anime, or some other such influences in your subconscious.
the thing is i never heard of muramasa sengo or saint peter until these dreams, and also i've never seen what chicago illinois looks like but the dream was pretty accurate, the sword that bound itself to me i later discovered was of japanese design, and the dagger of chinese design. i also found alot of old lore tyed to my dreams after doing research on them.
after these dreams i started research in angeology, demonology, and weapons of legend and myth. also i have dreams of my own future quite often but they become fuzzy until they actually happen. plus i can think of many incidents throughout my life, where my life should have ended but didn't.
Sounds like a fight within you. Your dreams are interpretting the inner demon (fears and regrets) as a physical manifestation. Thats why he spoke of fighting yourself. I take it your subconsciously assume where there is a demon there is an angel, so you want to embrace your metaphorical inner angel to defeat the mental/emotional demons. I assume you are or were Christian based on your subconscious interpretation of internal conflict.
