Between Dream and Reality

I know that I'm a sleepyhead but... I can't understand why does every single dream seem so real for me.

This morning, I woke up by a super big question tag in my head. I couldn't drive before, so why I though that I've ever drove a car? 

I always feel that I've ever drove a car but when I looked back on several years ago, I just took my driving course and I fail. So this is something impossible that I've ever drove a car.

Well, sometimes I can't distinguish between dream and reality.

Is it a kind of De Javu or something???? If you know what kind of phenomenon is this, please kindly tell me
