A dream is a way for the conscious mind to liberate itself. It allows the conscious mind to free flow and live through different scenarios that are not possible for it to experience during physical life.
As a person goes through their day, different things that they experience enter their subconscious. While in a dream, the subconscious takes what it experienced during physical life and creates scenarios that it can explore without limitations. Just as a person uses the bathroom to clear their excess physical waste, people use dreams to clear their excess spiritual waste.
For example, Patricia was at work when she met a much older client during a conference call. Patricia had a quick thought where she wondered what it must be like to have sex with the client. The thought only lasted a millisecond but there is a chance that she will have a dream about having sex with her client. Patricia might have no interest in actually experiencing that during her normal physical life and may be embarrassed if she remembers her dream.
Almost anything can trigger the subconscious to clear itself in a dream. For some, it may be something that traumatized them. For others, it can be something as simple as a billboard that caught their eye. Rather than making it a reality, the emotional and mental excess is played out and thrown away into a place of no time and space. A recurring dream can be an indicator that the subconscious is tackling an issue that has yet to be resolved.
Sometimes, the subconscious uses dreams to show people a glimpse into future events. It does this so that their conscious mind can be prepared when the event actually happens.
While a person is dreaming, their soul is still in their body. Their spirit is what leaves and experiences the dreams. Ghost sightings are the result of someone seeing another person’s spirit. That other person may be dead or simply be in the middle of a dream.
