Hi Nevuela,
Welcome to the board. It is obvious you have a curious seeking mind.
That is a trait that is sorely missing in todays world amongst many so good for you.
I really like what Wayward said above, that was my thought too.
Your friend sounds like she is very influenced by the power of suggestion. The bunker video at the summer convention was a masterpiece of psychological suggestion. Inferring that the world is about to turn on JWs who will be bravely hiding in basements ready to face the troops down when they storm the door.
Some JWs laughed or snickered and just rolled on.
Most felt a stirring of uneasiness (after all, it could happen, right?) and resolved to do more in meeting attendance and contributing to the world wide work.
A small amount of JWs have been fixating on the video. They think it is a subtle message within a message that only the wisest will see now and others will see later.
Your friend sounds like she might be in the latter group.
The Org was aiming its message at the middle group. They, like most manipulative groups, have little to no concern about the first or the last group - their target audience was the middle and the rest is collateral damage.
Your friend sounds like a good and gentle soul and no doubt she resonates easily to the "twanging of her emotional strings" so to speak. This video would have been fairly powerful in her mind especially if she is highly visual in her learning style.
You say she mentioned a couple of years ago that the Great Trib. might have already started....this is very common among JWs who are very sincere and slightly eccentric. To think they are the first to pick up the scent when the winds of change might be blowing. The Orgs record is one of them getting letters by the thousands stating what your friend thinks.
If it is popular enough, sometimes the Governing Body will put it in print as their own unique revelation. Anyone who thought it ahead of that time is considered "rushing ahead" and anyone who doesnt swallow it in its entirety once in makes print is considered "not accepting new light" and not keeping up with the chariot of God.
See how that works? The Governing Body and only they, keep a firm grip on the flow of information.
Again, welcome and I hope you continue posting. There are lots of nice people here.
