In some situations, we can use "were" with "I" although its grammatically wrong. But somehow it's being used many times, I don't know the situations any idea guys??
I were, used in the kind of contexts Irene has mentioned in her comment, has traditionally been regarded as a subjunctive from. It is certainly grammatical. The authors of ‘The Cambridge Grammar of the English Language’, however, refer to it as 'irrealis, indicating that it conveys varying degrees of remoteness from factuality.' Their view is that the difference between were and was in such constructions ‘is one of style level . . . were [being] somewhat more formal than was.
It’s not grammatically wrong.
We use “If I were,” “if he were” etc. for:
ex. If I were you, Unless I were you
Conditional Clauses (omitted “If”)
ex. Were I you
ex. I wish I were rich.
Doubts or Supposition
ex. Suppose that I were to join.
Together with “As if/though”
ex. He looks as if/though he were drunk.
Some fixed expressions
ex. as it were, would that it were
You can use this structure particularly when writing about something hypothetical, unlikely, or contrary to fact.
