Just bad combinations of food in my stomach. I've puked the first time, haven't the second. Both times I've had a short hallucination when I woke up the next morning.
E: Of course, I haven't hallucinated every time I've gotten sick and puked.
author=seiromem Oh, no, I meant AFTER I get sick, as in the morning I wake up an I'm no longer sick, but have an hallucination.
...Oh. I, uh, have absolutely no idea how one would fix that, unfortunately.
That's pretty strange, really. Perhaps you should see a doctor or something?
