Apocalyptic Literature - Part Two of Amil & Post-Mil Objections to Pre-Mil (Shorts)

What does Apocalyptic mean anyway? What is the Apocalypse? Does it actually mean "symbolic"? IS there symbolism in Revelation? Is it ONLY in "apocalyptic" writings? What about those numbers? Does thousand mean thousand? And if not does one mean one? Does seven mean seven? Who decides? Dispensational Pre-Millennialism or Amillennialism or Post Millennialism?
