Wikipedia says, "The phrase E ticket (or E ticket ride) refers to an unusually interesting, thrilling, or expensive experience. It derives from the admission ticket system used at the Disneyland and Magic Kingdom theme parks before 1982, where the E ticket (officially termed "E coupon") admitted the bearer to the newest, most advanced, and/or most popular rides and attractions."
So I say, thanks, Wikipedia, for explaining what the hell this song is supposed to mean:
Someone take these dreams away
That point me to another day
A dual personality
A strange untrue reality
They keep calling me
They keep calling me
Keep on calling me
They keep calling me
