There are so many flavours of meditation to choose from. The common theme is to empty your mind and to find stillness. I find this very useful and more refreshing than sleeping. Meditation can also open channels to the “source” and can provide mystical experiences. This is no longer considered as meditation of course.
If you want to take meditation to the next level, try using a crystal. The photo shows an Apophyllite crystal placed on the Third Eye during a meditative state. It is said that Apophyllite can increase psychic awareness.
