The Book of Revelation is the last book in the Bible. The title is taken from the first word of the book written in Koine Greek: apokalypsis, which means "uncover" or "reveal". This book was written by a Jewish Christian prophet that biblical scholars refer to as John of Patmos. John was in exile on the Greek island of Patmos as a result of anti-Christian persecution at that time. During his time on Patmos he had a prophetic vision of what is to come leading up to end of days and the return of Jesus on Judgement Day. In the vision John is to write down what is revealed (what he sees in his vision) and send it to the seven churches.
In the Bible God used dreams and visions (visions are “waking dreams”; see Numbers 24:4) several times to communicate with people. God used visions in the Old Testament to reveal His plan, to further His plan, and to put His people in places of influence.
