Yes, it's called Nirvana and I have been there after an accidental 80mg dose of 4-ACO-DMT. Had no prior preconceptions of what it was to be like or that I was even about to take drugs because I thought it was just a THC capsule. Long story short I had an extended out of body experience in which I lost the aggregates of reality (perception of self, time, and space) and was purely energy in the universe. Sounds silly but read this trip report and I had a very similar experience. And after studying Buddhism the year after that trip, the way Buddhism describes "ultimate enlightenment" and Nirvana are exactly what I experienced on the trip.
If you want me to give a more detailed explanation of the event and the trip itself I am willing just don't want to scroll bomb as it's a long journey and requires a lot of explanation.
So to answer your initial question, yes there is another reality that you may experience... but the only way to do that is by lifelong meditation and sacrifice, or a single perfect drug experience in which many things have to come together to achieve it. I did it completely on accident and my advice to you is to not spend your life searching for that, but rather enjoy this world we are in now and hopefully when you die we all get to that place, as I believe.
This trip report does a good job of explaining what I went through and experienced, but keep in mind I had NO prior knowledge of this drug or that I was even ingesting it. So it came out of nowhere and at the point before experiencing true ego death I had convinced myself that I had gone completely insane and that this was what my life would be like now and had no idea why.
"I was extremely afraid, mostly because i didn't know how much deeper i would be pulled in, and because i was painfully aware that there was no 'eject' button i could pull to save myself when things were getting too dark. It was at this point that i realized there was no way to fight it, and i had to surrender myself completely. So i stopped all resistance, cleared my mind, and just lay there hoping i would somehow just pass out and wake up in the morning as sober as ever. "
"I was just a ball of energy. Floating out there somewhere drowned out in waves of energy. At a point i realized that i was dead. My body was gone, I was gone. There was just the energy that used to be me. For a while i was afraid of my death, i wanted to go back, i wanted to live. Then i realized that there was no way to go back after seeing what i saw and feeling what i felt. I couldn't fit into the world anymore, i had to be pushed out. With these thoughts i accepted my death. Everything felt calm and silent. My mind stopped racing, and all the black and white energy around me swirled together to make an even shade of grey. It was incredibly peaceful. It's very hard to write out the experience after this time. There is a fundamental difference between knowing and understanding, and although i could attempt to make others know what i felt, it is impossible to make anyone understand."
