Is it normal to not know basic things about yourself?

I struggle to answer basic questions about myself.

For example if someone asks me if i like a particular food that they see me eating. I never know the answer. If someone else is with me i will ask them if i like it or not. If nobody is around to ask i tend to make up the answer. I get scared because i honestly dont know the answer. And my answer can be wrong like i say i hate something when i dont etc
