In that case you need a doctor or dermatologist to examine what they are.
they also kind of peel if i was to scratch or rub one
i actually have freckles all over my face and the ones on my chest are much bigger and way different
By your description it sounds like they are "freckles".
Freckles and appear anywhere on the body and will usually appear more when exposed to the sun and as you get older.
Ask your mum to look at them for you. Your mum will recognise if these are freckles or not.
