The hallucinations themselves are harmless. It's the side effects that you should worry about.
Your vision's not blurry. You're just looking at shit too fast. Try reading one letter at a time and from here on out speak only in syllables. If you break your words down you'll do less work in the long run, even though it's harder at first. Also recommended is closing one eye while having a conversation with someone face to face. If he's right there there's no need for depth perception. Make sure to alternate eyes every few minutes otherwise you'll get lop-eyed.
And lastly, don't listen to everything anyone says.
