What and If these two words are different, but if you bond those two together, they are something else. Those are most meaningful without the meaning. I never thought "what if" will ever pass my mind. There are many things I regret, while looking back on those things I always think what if I had done this?. As it results from today's reality will be different or I will in a different position. But this is not only me every other person in this world feels the same. "What if" this word when will hit your mind you never know, it can hit in the middle of the night in your deep thoughts, it can hit in your daydreaming. But thinking about it it's okay to do it. It can happen to anyone. Thoughts like, "what if, I acted like that? will it be okay today?", " what if, I take the first opportunity at that moment?", "what if, asked her/him first?, is today's situation will look different?", I seen some peoples they were not present in the last moments of their love one's and they think "what if, I was present there", we can't help it. It will come to our mind eventually. But while thinking it, we cant hurt ourselves. What if nothing exists and we all are somebody's dream?. The thought of "what if" is exciting, but at the same time it is scary. Did you ever think how much can we go deep with this thought?. What if it gets halo as deep as we get. There is no limit to it. What if, there was only darkness. We don’t know.
