decapitation dream

I went to bed on a full stomach, was really tired..

I was dreaming that the hubby and I were in some sort of shopping center, and we were shopping for a cast-iron pot stand (not holder) that sat atop a gas grill, so that you could leave a pot on top and it wouldn’t get too hot....it had three legs ( I have a pic but cant upload it - found it on the internet - and edited it to make it look like what I saw in my dream)
anyways - we saw it in this kitchen store - and it was sitting on top of a gas stove (colors were mostly yellow with streaks of red, but the pot stand was black, the stove top was white, and hubby and I were wearing blue shirts (which we actually do have)

in the next moment my dream switched, we were like in an arena, but it was on a creak (if that made any sense....people were fishing (I don’t have a clue but I think they were deep sea fishing in the creak) and a Chinese guy (I have a pic I found on the internet -again - but the guy in my dream had chubbier cheeks) caught a swordfish (have a pic of that as well, and it was mostly blue - but the same shape as the pic I have)
he was bringing it in the dock - and at this time I was on one side of him looking at his back (like a camera view) and I saw the fish jump back to life...he was struggling with it - and it was somehow lodged where he could get a chainsaw started and he was going to cut the head off...the 'camera' (my body) changed view to where my hubby and I were standing facing him and the tree - watching him struggle...some other guys were trying to help him...I can remember the tree being brown, but the leaves up top were green, but the sky was the same yellow as the shopping center...the chainsaw was a one sided blade (don’t even know if they make them - but it was a dream!) and one of the guys trying to help him tried to grab the blade of the chainsaw (the side without teeth) and pull it - but wouldn’t budge, and it was still running...don’t know what happened to the fish (think someone in my dream mentioned the head being cut off - but I don’t remember seeing it after the chainsaw got lodged in the tree) and then in the next moment the chainsaw popped out, and the Chinese guy fell over..when they went to grab him he was head less....what’s weirder is that there was hardly any blood, and the skin around the neck was grey, and his head was grey, and the guy had a shocked look on his face (think the movie the grudge)

The water was see-through - but river green...

The deck was brown....it seemed to be in the middle of the day..I felt a severe sense of panic when the dream came to that point, and immediately woke up

what’s disturbing is I went to bed at 8pm, woke up at midnight from this dream, and could not fall back asleep, as this dream scared me awake, and every time I closed my eyes I saw this guys decapitated body and head and expression - and couldn’t fall back asleep.....

This happened mere hours ago - and I have nothing pressing or disturbing - the last movie I watched was departed - and we do not watch horror flicks...the only thing I can relate to is I was watching discovery health and a woman had her foot cut off with only local anesthesia...

any help or insight would be great...thanks....
