Nightmare

I dreamed I was missing, I was so scared but no one would listen because no one else cared
about that.
After my dreaming I woke with this fear, and I do not know why I am feeling fear and it is just a dream. When my time comes I remembered the wrong that I’ve done before going to sleep, I used to spill my milk without the knowing of any one.
So that the reason of feeling fear that made me dream of being missing, the guilt that I have done which is spilling the milk.
So, the conflict inside me is that, I do not like to drink milk, but my parents forced me to drink it, and I do not like any one to force me to do anything, so I used to spill the milk and I do not like to throw any kind of food or drink and I am feeling very fear from God because throwing any kind of food or drink is considered as a fault from a religious point of view.
So, What Shall I do to? I really do not know.
