One-Eyedness
Scholars have said that if a virtuous person dreams of being one-eyed, it might indicate that they are a truthful believer in their testimony. If the dreamer is an evildoer, it could signify losing half of their religious commitment, committing a great sin, or experiencing distress or a severe illness that threatens death. The dream might also indicate harm to themselves, a family member, or the loss of blessings.
