Help I know I might be over exaggerating and stuff and I try not to let it get to me but it’s very strange. My brother who is old enough to mature preteen likes to run around the house hissing and growling at people pretending he’s a dinosaur. Usually this would be something to pass if and say “oh well he’s just a kid” but not only is he a preteen but he genuinely thinks he’s part dinosaur. This has let to some extremely embarrassing moments is public. One time we got asked by a waiter at a restaurant if my brother was ok cause he was making strange velociraptor noises and sounded like he was having an asthma attack. So question is should I take him to a mental hospital or doctor?
