I know we all get some CEVs before we go to sleep. And we get them when we smoke. I last smoked about two months ago, and my CEVs (I only get them before bed) are much stronger now. I used to get the occasional fractal, and now they happen more. I used to get the occasional song too. Like a song my mind is making up, and it just keeps going, and I have no control over it. I've never heard the song before. I now get these several nights a week. This is normal, I'm assuming? Maybe the weed just unlocked some creativity. It also decided to unlock a nasty anxiety disorder.
Haha, wait 'til you trip on something heavier and get HPPD... But yeah, it's not a big deal.. the anxiety you might want to keep in check though. Weed makes a lot of people anxious when they first start smoking but it should improve with time.
