Any other 2 years olds do this. Or doesn't matter the age...

For the past month or so my 2 year old has been waking up screaming,kicking, crying,.. like he's scared out of his mind. Not really waking up but his eyes are wide open but he's still very much asleep. Nothing soothes him. If I try to hug him or hold him hell start hitting me like I'm hurting him.. he scares me at times cause it's like something/someone is hurting him or scaring him and I can't figure out what!! 😢😢 I feel helpless. He calmed down after a while but i dk what's triggering it..
