Palm reading answer
What does an overlapping heart line mean?
What this means
First confirm the mark is a shifted or partly overlapping continuation of the heart line, not a long double heart line or simple photo shadow.
Palmistry often reads breaks and disruptions on the heart line as emotional challenges; overlap can soften that by showing continuation, repair or a changed chapter.
Compare the later segment's clarity, nearby islands, chains, downward branches, the head line, marriage area and both hands before making any strong claim.
