Déjà vu so extreme that I can’t tell what’s real
I once had this feeling while being stoned. It was maybe my fourth or fifth time smoking marijuana. For a good two or three hours, every moment I experienced, every conversation I had, I had the feeling that I&#x27;ve lived through it before. A constant Deja Vu.<p>I knew I was stoned, but it still freaked me out. After talking to my friends about this (while still being high), I was able to enjoy and explore it. I asked my friends some questions to which I didn&#x27;t knew the answer. Still, when they answered me, I <i>knew</i> with great certainty that &quot;I&#x27;ve heard this before&quot;. My friends came up with all sorts of fun experiments to further explore my state.<p>I later read that this feeling (i.e. a normal Deja Vu) presumably is caused by the brain storing information immediately into long term memory, instead of keeping it in short term memory first. When the information is in long term memory while you are still experiencing it, you get the feeling that you&#x27;ve experienced it before.<p>Scratching the surface of how my own brain works (and can be rewired), was extremely profound and quite unsettling. I stopped smoking since.
