meaning - Difference between 目覚める and 起きる

I searched for both they mean to wake up.

When do I need to use 目覚める and 起きる.

Answer

起きる literally means "to get up", while 目覚める means "(your) eyes are opened". This can mean either literally (i.e., waking up from sleep) or metaphorically (come to one's senses, come to a realization).
