Connections of dreams and spiritual world

If you ever wondered why science has its limitations and many scientists have seen spirituality as being the final conduit to understanding the nature of humans. During the dreaming state of sleep, we experience the different levels of consciousness and receive input from the different dimensions of the spirit world. Through dreaming, we have special access to our spirit within.
 
A dream may be of a physical, mental, or spiritual nature and may deal with all manner of psychic manifestations.  
 
We look at the relevance of dreams and the role of dreams in taking us to the dimensions of the spiritual world. The experience of scores of people speaks for itself. Oftentimes, people have dreams and dejavus. In the question of dreams and spirituality, it is hard to strike a direct connection. But, there does exist a distinct relationship that necessitates addressing.
 
We have all experienced dejavus at one point or another. Dejavus, it is said is caused due to the release of a chemical in the brain. People sometimes dream about something and the dream comes true in reality. Sometimes, dejavus are linked to occurrences in one's dream. 
 
In dreams, we often get messages and are able to locate weird details in an already occurred incident, something we wouldn't have while such an incident was taking place. Science has been able to prove this. Dreams and spirituality, thus, it can be said, have some form of connection that is slightly beyond human capability to comprehend.
