hello people!

I've been wondering if dis-appearing and re-appearing is real, as in both in movies, witch-doctors, cultists, witches and wizards etc.

Just wanna know, how does it work, where exactly is the person that dis-appears before appearing, and how do they find their re-appearing point?

Is it that they just put lagos in mind and gbum! They are in lagos?
And even as at that, do they also put the street in mind??

Please o someone help me before i go nut
