This section of the web-site starts out with the following wording...:
«The Mandela Effect is NOT False Memories»

Core Web-Site @ https://fionabroome.com

EXPECT to be ABLE to ACTUALLY NOTICE said «Butterfly-Effect» (currently more-popularly known as Mandela-Effect; similarly to how the phenomena are now called UAPs rather than UFOs) once you are CONSISTENT with your «HAND-Written» Records/Journals about what you see/witness/draw/etc., over the next few months. A company logo that is famous ? DRAW it (with HAND-Written Time-Stamp). A song-lyric of popular-songs ? HAND-Write them down (with HAND-Written Time-Stamp). A popular «meme» that has spread across the Inter-Webz like wild-fire ? HAND-Write its wording (with HAND-Written Time-Stamp). A «Global-Narrative» being pushed onto the public ? HAND-Write down the «news» (be it 9/11, JFK-Assassination, Assassination-Attempt on Donald Trump, etc.) that was reported (with HAND-Written Time-Stamp).

I absolutely REALLY hope that I am NOT the ONLY «human» here on Earth who seems KNOW (or at least have a very good idea... I think I do anyway) about what the Harvey Group has been talking about... ESPECIALLY when they tell you to HAND-Write down what you witness ! Q_Q
