How can one verify that the mentioned visions are indeed genuine visions of the Prophet, peace and blessings be upon him, especially with the presence of historically inconsistent details?

If your vision in a dream matches the description of the Prophet, peace and blessings be upon him, then you have truly seen him, for Satan cannot take his form. Among his characteristics were that he was of medium height, neither tall nor short; he was fair-complexioned, neither intensely white nor dark; his hair was neither extremely curly nor completely straight.

He had broad shoulders, abundant hair that reached his earlobes, and he wore a red garment. His hands and feet were thick in the fingers and palms, he had a large head and prominent joints, and fine hair that extended from his chest to his navel. When he walked, he leaned forward as if descending from a high place. He had a large mouth, long eye slits, and little flesh on his heels.

Regarding the sin you committed, repent to Allah for it, and if you took anything from your brothers' rights, return it to them.
