In this crazy-hectic world, it's not weird to want to tap into a connection with something bigger than yourself — which is an excellent reason to be more spiritual.
TL;DR: Being ~spiritual~ can mean whatever you want it to, but these things can help get you in touch with yourself, others, and the world around you on a new level.
And obviously, feel free to be skeptical and just do some of this stuff for shits and giggles because... why not?
