I feel like I've been stabbed before but I can't remember
How can you not remember whether you were stabbed or not.
I couldn't say for sure, there were some important details missing
That's a pretty important thing in your life. You should try to remember it better.
Yea. I will continue to try and remember because I am surprised I could forget something like that.
It is reasonable that you are going to forget certain things in your life. However, forgetting whether you have been stabbed or not is pretty unlikely unless you dropped to the ground and hit your head afterwards. Maybe you can ask your family if they remember you ever being stabbed and going to the hospital.
