I actually think as a layman, that people just confuse opposites period. I've actually heard Japanese people say in Japanese, "other left" (context: contest with blindfolded driver getting directions from seeing passenger). So my evidence is that plus other similar occurrences, across cultures. I think some dyslexics may be trying to explain their experiences using something that isn't particularly diagnostic (though they have a real issue, opposites isn't the real issue) Like a heart patient who says "I hate climbing stairs" We all hate climbing stairs.
