What is a spiritual awakening and how would you know if you had one?

lately ive been really questioning wut itz like to die and y i wuz put on this earth. i think about death alot. i mean a whole lot. i think about if god iz real. i think about if theres even a after life or if lifes jus starts over after u die u know wut i mean, like if your just given another life to live as somebody else with no memory of your past life..it sound weird i kno n theres other things but i jus cant explain it
