Struggling with pre-sleeping thoughts

Can you go to sleep easily? 

My answer is mostly no. 

There are those nights where, somewhere in your brain or heart starts to think/feel things that you do not normally think in the day. However, just as you hit your pillow and ready for your good nigh sleep, you simply just can not go to sleep. Yes, I am exactly like that right now. And most nights are like this. 

I get into bed ready to fall asleep for the next day which is always busy with things I have to do. But my body just does the opposite and wakes its self up and think about things like...

'I wonder why people exist' 

'Do we all have a meaning to live in this world?'

'I hope it is not hot tomorrow.' etc...

These are just some examples but when I want to calm down and have a good night sleep my brain goes "nope! I am just going to start thinking about things". i guess that is why I am writing this post. 

I wonder what are things that I could do before I go to sleep in order to make me go to seep. If there any suggestions I would happy to try! 

I hope my readers are able have good night sleep! 

I will do my best to fall asleep. zzZ

See you later!
