Is it normal to block out your trauma?

So I understand that people do their best to not think about their traumatic experiences and like legitimately block it out, but whenever it pops into my head it's a blur. My trauma was rape/pedophilia which was not the highlight of my life, but whenever something triggers in my head it's like I "want" to think about it but everything just sort of stops. I can't really explain it. It's almost like when you try to remember your dream and it won't come back to you and you only remember bits and pieces. I was driving to work the other day and the song I was raped to played and I remembered what it sounded like but I didn't remember the name of the song (although I definitely knew what the song meant to me) and it brought me back to when I was actually being raped, but I couldn't actually picture any of it in my mind. I don't know how to explain this properly. It's like when you read a book about something and explain it, like you know what happens, but you don't actually know what the person is feeling. I almost view it as a third person thing. Is this normal for trauma survivors?
