How to experience a high without drugs?

HI there :)
Gorgeous day out eh, I have the answer your searching for right here :o actually two (but the second is unusual)
First I suggest finding a flotation center near you and book an appointment! If your unknowledged on this topic do a bit of research. If your a person who meditates you know the sort of personal clarity that it can bring but now imagine getting into a huge tank that is filled with salt water heated to your body temperature and sealed from light and sound. Experiencing this floating sensory deprivation for a duration of time (1-2hrs) can cause your brain to do some funky things. to start the mental conversations you have with yourself have a level of clarity and self-awareness that is just…. I find it hard to explain but quite unparalleled to the sober mind! Next your imagination and mind is just going nuts because its not used to sensing nothing for so long so you could easy experience mild to strong hallucinations that are similar to lucid dreams in the sense that you have greater control over them than you would a drug induced hallucination but have a very real, emotional and safe feel to them.
Secondly I’ve had some wild mind experiences when coming down from a long binge of drinking and being sleep deprived. THAT can make your mind do some crazy things too. Next time you have a hard night out with friends instead of going home and crashing try staying up long into the morning by yourself or with close friends to have intellectual inebriated conversation, strange feelings and thoughts can definitely occur :D
Of course these are all suggestions from my own experiences and I can only imagine not guarantee that others would feel the same effects in similar situations :)
Cheers!

I may be too close minded to contribute to a satisfactory answer, but from personal experience I would have never encountered or felt the things that I have, had I not taken mushrooms. I had tried to open my mind and heart before but I’ve always felt as if there has been a barrier that stands in the way of opening myself to those emotions. Some may and probably will argue that it was my own mind creating those barriers, but I cannot stress the importance of how hard I tried to remove those barriers only to have the end goal slip away into self-indulgent self-loathing because I was unable to do it. Mushrooms changed that, and at the very least extended my emotional horizons to a point that I was unaware even existed — successfully helping me not only vault over those barriers but land in a place so far beyond my original imagination that I could hardly believe or comprehend it. I guess what I’m trying to convey is that the only problem with getting “high” without having taken any drugs is that I don’t know how you could compare it, but if you can do it and somehow simultaneously have the perspective or extreme empathy to know what those other drugs could have done for you, then more power to you.
