I've never tried the original PSVR, but I've used the Vive and Quest2. The Vive was my first try in VR and I remember that it was a learning curve to like tell your body it wasn't real, so you didn't "wobble" irl on the floor while moving ingame. I'm now at a point that this is not an issue. Still, I remember that after that first VR experience, it felt like my brain was still in "VR mode" several minutes after the experience. I remember driving my car after a session and there was a queue of cars infront of me. I got the feeling that I could just use my hand to select the different cars and then just move them out of the way. Trippy feeling. I've never had that same feeling again during my Quest2 time. After my first experience with PSVR2 in Horizon and GT7, I got the same feeling agian. My brain was obviously tricked on a more subconscious level than I would know, because after my session I picked up my phone, and my brain was obviously still in VR mode, 'cause I got a feeling I watched my phone in VR. Surreal feeling. Obviosly I knew I wasn't but the feeling was kinda same as when you experience Déjà vu.
It's obviously because the VR is so good that the brain is fooled, even though you know it's "fake", but still some synapses say's it's real.
Is it only me that's experienced this? I've never heard anyone talk about it, so i'm actually curious to know...
Edit: My Vive experience was obviously some years ago when it was brand new.
