Slight nightmare

Hi guys new here but anyhow....

I have been trying to recall my dreams here lately to start having lucid dreams. I normally do not recall my dreams and have dreamed lucidy maybe once or twice in my life (great experiences). So anyways i had this dream last night or maybe it was a nightmare but i didnt wake up freaking out/sweating or anything odd. But this dream has been on my mind all day. it is really messing with me so i want to share it and get some input on what kind of meaning it had if any. So here goes:

I was in my room and it was very dark. I could only see shadows but i could make out everything within a foot or so of me like i was illuminating everything but the darkness was so intense i couldnt penetrate it to see well enough. I had an intense pain in my left light. So i pulled up my baskedball shorts to check out what the issue was. I had a grey-green cyst looking place on it the size of a silver dollar. the skin around it was infected and jaundice looking...corrupted was my initial though and that stuck in my head throughout the dream. I HAD to get rid of it to get rid of the pain. So i get my thumbs around it like its a pimple and i squeeze. the pain was intense, so intense i saw stars and stared to fade in and out of conciousness. Just before i completely blacked out it bursted....slowly. It was long and stayed intact as it came out. once all of it had forced it way out i could see deep inside me leg...all of my tissues and a little bit of bone for just a split second and then blood started to well up inside and pour out. I thought to myself "i need to get to the bathroom and stuff this with gauze before i bleed to death". So i limp to the bathroom because the pain is still very bad. I get there and grab some gauze and start stuffing it in the hole which was extremely painful. No matter how much i put i kept bleeding. After fulling my leg full i was sitting in a pool of my own blood which was getting increasingly bigger. I started to feel like i was going to pass out, went in and out of consciousness a few times and woke up.

Any input would be great. Anyone else experienced intense REALISTIC pain in a dream?

Thanks
