Two different pathophysiological mechanisms to explain the phenomenology of the visual hallucinations as a result of a wide variety of conditions have been proposed.

Roughly 2 hours and 42 minutes: Titanic struck the iceberg at 11:40pm on the 14th April and sank at 2:20am the next day. When the Titanic hit the iceberg the bottom four floors started flooding and it kept on going until the whole ship split in half and sunk to the bottom of the sea where it split once more into three pieces when it hit the bottom.
The Titanic sunk over a century ago on April 15, 1912. The iceberg collision ripped open Titanic's hull in several places, including her five watertight compartments. The Titanic sinking transpired over two and a half hours which was relatively fast for a ship of such size.Titanic carried 2224 people of all ages, genders and class that fateful night, and only 710 escaped in lifeboats and later rescued by the RMS Carpathia. 1514 people died in the icy waters.y 01:35, as Lifeboats #15 and #16 abandoned the ship, all of the boats in the second-class portion of the boat deck were gone. Six lifeboats remained on the ship, all in first-class, with a combined capacity of 293 for the estimated 1,800 people who remained on the ship.
