It could be both spiritual or Carbon Monoxide from closed windows or sleeping on the floor. As soon as I slept on the floor that I did not do for ages, I had a weird seemingly nonsensical dream of a demonic person killing people in a small room in daytime as they were sat down, and pointed to the last one with a finger and the "shadow" killed him. It may have been a message from my mind saying there is a harmful dark cloud "Carbon Monoxide" that can kill people, or it could literally be a strange vision.
I also had the same sort of thing you had two other times, but not on the floor, and in the dream was a rushing wind of invisible forces shaking a dark bedroom with a sort of cloudy light shaking around also; this left after saying "Jesus help me" in the dream a few times. It was a bit like night-terrors but asleep. I have no real clue what this was about.
I had another one which had me somehow being hunted by a dark wooden golem/doll triangle headed, where I was at the top of a cliff by a fortress sort of japanese castle etc and it at the bottom in a cave, and I suddenly was hunted from the dark cave through the castle and then joe-rogan started fighting the wooden doll that turned into a floating and following giant demonic angel/arabian statue bearded invincible being in a castle game like indoor court, saying something like "yes, fight me joe" with no effect on the angel getting smashed in the face with power jump punches and Joe making a "caw" sound each time. Then I woke up a bit freaked out and heard the bird cawing outside my window. Though this only happened after I got confused and started ONE day of trying to keep sabbath. This seems to be a strange dream but also a warning to not try and "save myself" in any way, otherwise I will lose like Joe. That name also links to me in a way. Or it could all be nonsense, but I thing I will not get confused about sabbath again...
I get some weird dreams, some too personal to mention, but obvious warnings, much more obvious than these. None of this really helps with daily life, so just carry on as a believer etc.
