Vision Of Ouroboros

[DTone]

One morning, in the moments before waking up, I felt a buzzing in my body, and a light trance, then I felt positive bioelectricity, but I couldn't hear anything clearly, but I had scattered colors in my vision that formed a face similar to mine, then I saw a snake eating itself, and my eyes started to shake and I woke up.

I have tried to understand what it was, does anyone know the meaning?
