I came in here late,I didn't happen to watched IndigoTeen98's video on this.Below is just my little experiences

I'll explained 2 simple ways to do precognition.I'm sharing my experience is precognition.You can use tools like a dice or zener cards.You need to go into a meditative state,relaxed, and focus,let the image pops up in your mind and then throw your dice or select the card and turn over it and see if the anwser is correct.

The second method,again do the same state of meditation,visualize you are turning the card over and see what is it and verify that after that.

Have fun guys
