Dreams...

I am very and truly sure that everyone had dreams..

The confusion that I want to bring up here is..is it normal for us to have dreams every night while sleeping? Because I am having dreams every night and it is hard for me to have a sleep without dreams..

I thought everyone dreams everyday but one day when I was having a talk with my friend about dreams then I knew that not everyone has dreams during their sleep..

So..may I have your opinion about this dream thingy?
