This video contains perhaps the best explanation of what is going on with regard to the Mandela Effect events that are being noticed with increasing frequency.  If you want to skip to the explanation of the Mandela Effect, you can go to 47:27.  But the earlier information in the talk is great, too.

Her tips:

• Know that this world is all an illusion.
• You want to move and don’t look back.
• Work on getting rid of your karma.
• Forgive other people and yourself.
• Treat people the way you would want to be treated.
• Let go of fear.
• Don’t believe everything in the media.
