Universal Migrator Part 1: The Dream Sequencer (sometimes simply referred as The Dream Sequencer) is a progressive rock album released in 2000 by Dutch multi-instrumentalist and songwriter Arjen Lucassen, and is the fourth album of his Ayreon project. The Dream Sequencer features a musical style quite disparate from its counterpart Flight of the Migrator, telling the story of a trip through time from a variety of perspectives, it features a prog-infused atmospheric feeling, with a softer and more melodic sound than that of Flight of the Migrator.
