Right!

a. No! "I feel weird" means there is something wrong with my body. For example, I am feeling dizzy or sick or my legs are tingling or my hands are numb. Feeling weird is a cause for concern. You may be about to have a heart attack or to faint and lose consciousness. For your meaning, you would have to say, "Something weird is going on (happening)."

You are absolutely correct. I believe that you answered your own question. :)

It's weird when someone, who is as weird as I am, say I am weird as them , yet I can't help feeling weird myself when I hear that ,as weird as it may seems to you.
