Is it normal to see yourself from above when you're being abused

It’s normal but what you should be more concerned about is summoning up the courage to report your abuser

Unfortunately, it's an automatic defense mechanism used to protect the mind in extreme circumstances.

However, I dislike the comment telling that you need to get the courage to report. Being abused and stopping it isn't a lack of courage, it's something that's unexpected, scary, and confusing. Stopping abuse is about having the support of those who will help you stop it, someone to believe this is happening to you and willing to give you the time/resources.

My advice, talk to someone you can trust 100% and has your safety in mind; don't stay silent. Tell a friend, teacher, school nurse, a friend's mom, etc; as long as you know and trust them it's a step in the right direction.

Yes, this is very common when someone is being sexually abused. Especially for younger people.

Yes

It's called dissociation. It and its close relatives derealisation (where what's happening seems unreal) and depersonalisation (where your body doesn't seem to belong to you) are common during any sort of traumatic event. It's also not unusual for everyone to have random moments of such feelings at other, non-stressful times.

It's a useful coping mechanism in times of crisis, but it can become a serious problem if it becomes permanent.

Wow I didn't know about this so I could not vote. I have no advice due to lack of knowledge on the subject, but I truly hope you can find a way to stop the abuse and to heal.
