🤔 what if? Question about the Bible

Re

I don’t know much about the Bible I have never read it and don’t plan to. So if I’m way off I’m sorry. I know some will be mad. So if I remember correctly in revelations it says the dead will rise. So does that mean like the dead will be like zombies or will they be (whole) like living people? I know the Bi me not real and it’s not going to happen. I was just been watching walking dead and it got me thinking will what if that the way the dead come back. I’m not religious and I don’t believe in the Bible at all so I’m sorry if you do and I make you mad. I would ask my stepmom but she would be mad and not talk to me about it.
