Sorry you are underage but if some day you decide to play older games you may notice that in Pokemon, dreams are just other timelines.
Even the true ending of the Indigo Disk where you get the childhood book of the professor of another world ends with you waking up in your bed, but with the book. Terapagos is the pokemon that makes dreams come true by taking stuff from other worlds, just like the professors' dreams of paradox pokemon from a primitive/futuristic world came true with the machine.
