Soul consciousness in dreams

So my Fitbit tracks deep sleep, light sleep and rem sleep. Even when I have long lucid dreams or long vivid normal dreams, the data for rem sleep is a very small amount of time. Is it possible that the soul takes over in consciousness when the brain isn’t maintaining consciousness?

I got this idea. Based on near death experiences where people see things when clinically dead. Therefore the brain isn’t responsible for that consciousness.

So could that come into play in dreams as well?
