Well about a month ago me and my 2 friends split a fourth of shrooms. We had a really great time.(Oh and we blazed it 3 times to enchance the effects) Well now, several weeks later im starting to have these after effects that i can only really attribute to the mushrooms and was wondering if this sounds normal. When I stare at something, my floor for example, it starts to kind of shimmer and move around like little waves. And some times out of the corner of my eye I will see this brownish black thing kind of whiz across my line of sight then dissapear. This didnt annoy me at first, but now several weeks later it is statring to get really abnoxios. Well any input is appreciated. Thanks.
