Sometimes I wonder how experiencing an altered state of consciousness feels like, since I have never done any drugs. I and my friends realised that for us it will always be the feeling when we watch sunsets on a beach or look at the high mountains and feel a sense of freedom which is unexplainable.
The way I perceive sound and time all changes. It's bliss. If you've never done it, go to the mountains at least once - trust me when I say it's pretty addictive.
Quoting what @Khan.Isa
said the other day, "zindagi mein jab sari achi chizen khatam ho jayegi tab buri try karenge."
