do i exiset

well i always thought like do i really exiset or all this around me is just a dream just a charecter in my mind and i try to prove that i'm here but i can't prove any thing with out assuming something else first so does any one have the same ideas like me or what's your weird thought that people laugh at or your too shy to share with some one
i really need to know i'm not alone
I'M ME AND PROUD
