Lexical hallucination

[trochee]

On a totally different note, I have found myself lexically hallucinating a lot in the last few days. Maybe it's because I'm not getting enough sleep, but I have caught myself after misreading something badly at least three times in the last day and a half.

For example:

• (In a Vietnamese restaurant): peacefully enjoy your meal (It really said please fully enjoy your meal)
• On a bottle: Registered water (it really said Purified water)

I can't remember the other examples -- I think I'm just tired -- but has this ever happened to anybody else?

Perhaps I'm spoiled by my usual super-fast reading speed.
