Wow, sounds like you heard someone say "Eject, Eject, Eject!"
Glad you survived the incident. Could have been much worse.
Illusion made a good point in you analysing what happend and what to do next time.
That is very important in becoming a better rider, by learning from mistakes.
Start slow and get used to the bike.
It takes less than a split second to find youself suddenly in an "Oh $#!+"situation.
