Some of these have been around for a while or remind me of some, my crunchy new-age grandparents were hardcore into the NWO order stuff. Some others I recall

• NWO stuff: North America would become the North American Union and forcefully adopt the Amero as currency. This was the pretext for the eventual merging of the EU and NAU to start total domination, pretty sure the UN was involved in this one.
• Stargates are real and the the US has bases on the moon as well as Mars
• Some water alignment thing, that you can put a logogram or something under a glass of water and that changes its properties to be better (‽??)
• The Philadelphia Experiment
• Roswell is responsible for technological leaps, and the powers that be have been slowly releasing things to evade suspicion
• Mayan calendar stuff
• Hardcore distrust of medical doctors and hospitals
• Fluoride - mind control, it’s a neuro toxin!

There’s others but those stick out.
