Nearly all my dreams are really realistic.I know that every dreams is a sign. Dreams explain the way you feel about something or about your health. But my dreams don't do that there visions about small details. And I find that weird because I don't realise them an till it happens.so my questions is hou can I train that or control that.

We often make things happen in our life or find ways to connect things.

Often dreams are just that, a dream and don't mean anything and seldom any are "signs"
