Is it normal when i was a child

yeah kids love attention, when i was a kid i used to crawl around on my hands and knees pretending to be a dog to get attention, kids are weird!

So did I. I definitely think it was an innocent childish attention seeking thing.

Overdose on aspirin or something. You'll be in the hospital

I used to lay on the floor pretending I was dead and to see if they would notice me

...dude, I jumped off a balcony to get in hospital.
everyone wants to get in there ONCE,
just to get everyone to come see you,
to make you feel proud, or more wanted.
humans are meant to be that way.
we all want to be loved, to get attention from everyone,
etc, etc.

unfortunately, I had to walk around wearing a friggin' piece of wood on my leg, covered with bandaids, and an arm that couldn't be used for a month.
after that, I still couldn't walk well for a week.

I always wanted to have some kind of problem that made me stand out and made people pity me

It's normal. I used to fantasied about being kidnapped and unknown to me at the time, to develop Stockholm Syndrome. There were times, where I would wish that any injuries I had would be serious enough to make me go to the hospital. I was strange kid.
