Dream Levels were introduced in Marathon Infinity. These levels have a strange setting and usually have enemies not encountered in 'normal' levels. They usually have multiple exits, that may even lead to levels way back. They tend to have some bizarre poetic terminals. The idea of dream levels has been recreated in various fan-made scenarios.
The first dream level is Electric Sheep One (Level), in which you start on a small platform above the lava. You then have to hit a switch, thus waking a lot of Ticks and a black Enforcer. You merely have to head to the right platform to finish the level. This is copied in the next electric sheep levels. But the levels that follow are even weirder.
