Irrelevant thoughts. That it is false.

Can't control random irrelevant thoughts about any thing which comes in the mind though he knows that it is false. talks in the mind, thoughts go away, another thought comes. able to carry out his daily tasks but recently it's frequency has increased. Obsessed with things being stuck ex(bricks, stickers, clothes or any thing). Is not deprived of sleep and goes to office. feels the urge to count things and curiosity to know about unnecessary things. Again talks back to realize it is false but the thought stays in the mind for a while. For ex :- hitting a cricket ball/football any object, the mind thinks that the things are getting hurt, then talks back "how can a non living thing get hurt" though disappear then come back when it comes in front.
