Thread: Why can't I remember how the dream started?

I always recall the last part of the dream but i never remember how it started. Is this common?
And how can we learn to remember how it started?

my dream recall is much better. but i never remember how it started and how it lead to the last part.

or do dreams generally not have a beginning?

like i dreamt my sister and her boyfriend were together in my room talking. But i dont remember how they got into my room , what lead them to come. i dont remember how they came or nothing.
