True/false to make worlds

I have an astral . I travled to best friend in his sleep

Creating of another world sounds exaggerating, but creation of a dimenssion is possible, yes. Human minds hides amazingly huge power, out of our imagination. However, this whole power is inactive and we're completely unaware of it. We are very sophisticated beings.

you cannot create a physical world, but it is believed to be astrally possible. anything seems to be astrally possible which is why some don't believe in the astral at all instead it's your imagination. personally it's a personal belief so research the astral and draw your own conclusions.

as for magical girls and transforming no, these are not possible. there is a difference between fantasy magic [seen in movies and tv] and real magick [that real life pagans work with] with fantasy magic anything is possible [flying on broomsticks, invisibility cloaks, physical transformation] real maigck is actually an energy found in nature. those who cast spells tap into this natural energy and direct it through spell casting to create a desired change by essentially effecting the energy surrounding a given situation [say you cast a love spell on your crush, you might find yourself bumping into them a lot more. he doesn't necessarily like you now, but you've been given opportunities to talk to them] i suggest finding some articles/forums on basic information and what spells can/can't do before casting spells.
