I would want to continue my life as a spirit, but in this case, I would come back as my son's son. The only annoying thing is to relearn everything in school.
Either a male lion or a human again. A male lion doesn't do much in the day, sleeps most of it, protects his family, goes hunting, then eats. But there could be some drawbacks when being a lion, you might get hunted by people, or captured then put into a Zoo. I'd like to come back as a human because I'm used to it, and I like being able to do all the things that I'm able to do now.
I would come back as a human. If it were myself, that would be strange for all the people who knew I died. i would also want to know I reincarnated if I reincarnate as a human.
