nrishiraj,
Subconscious is a psychological word, and what it suggests. Some may say it is a motivating factor for dream scenerios. The word unconscious is another word for the same.When something is brought to consciousness, it builds on understanding. How a person utilizes the mind is up to them. Mental process doesn't require an entity,imo.
Soul/spirit are metaphysical words. There are various ideas about how this relates to the subconscious. For instance, a spirit is motivated by it's level of evolution, imo.I believe dreams are dimensional travel, therefore, out of body. The use of a vehicle may or may not be necessary. I guess it comes down to defining or recognizing energy?
My simple answer for a very deep question. [:)] This is why I wish to understand more.
Other ideas are possible.Quantum physics is interesting, but I can't get a handle on it.
I apologise if this has already been answered.
When we dream does our soul / spirit leave the physical or is our subconsious doing it all?
I'm a little confused.
