I got my rift this tuesday, and I've been using it a lot since then. I haven't been experiencing many side effects except from a bit of nausea the first day.
Today when I woke up however I got the strangest feeling. I thought that I was still in the rift. It's difficult to explain what it felt like, but when I stood up and looked around (it was still very dark) it looked like my room was just virtual. It only lasted for a few seconds and I was very tired so that might have added to it.
The feeling didn't disappear entirely though, and for a good hour I kept getting that sensation of my surroundings being made up of pixels, and when I brought up my phone to check the time, it hit me how much that motion looked like the menu popping up in Eve Valkyrie.
I've had some problems with anxiety before so this was not a nice or "interesting" feeling for me, it just made me uncomfortable. I really don't want to wake up like this every day lol.
Am I actually crazy or does anyone know what I'm talking about?
