The Taste of Nightmares
Pepsi. Not that pepsi tastes bad, but that's what nightmares taste like. Sometimes nightmares, on rare occasions, can sometimes taste like expired milk, but that is a 1 in 1000000 chance. Now that you know what nightmares taste like, what do dreams taste like? Crackers.
Duuuuuuuuude, the Taste of Nightmares is Pepsi.
