When you wake up in the morning, your mind and body are awake. It's as if a switch has been flipped in your head and you start thinking about different things, and at the same time, feelings and sensations come to life in your body. In this way, we engage in various activities and experiences through the interaction of our mind and body.
Then, at night, when we fall into a deep sleep, the soul awakens. The soul separates from the body and emerges in a state of full awareness of one's spiritual being and feelings, called 'atman'. At this time, the soul engages in various activities and experiences in spiritual reality, where all objects and spaces are energized.
A dream can be seen as a recollection of some of the events you have experienced spiritually while asleep. This is possible because when you have a stimulating experience in the spiritual world, your mind becomes lucid, and your brain waves are activated.
