I KNOW ITS A DREAM BUT WHAT WHAT DOES IT MEAN?

salam aleekom my brothers and sisters,i want to share with u a dream i had 20 days after i become a muslim,it was on 11/12/12 as i retired to bed.i know most of u will think its fiction or maybe a fairy tale but i tell u this is not comedy.as i lay asleep on my bed,i saw a someone come to me,he said he was a ghost BUT I WAS NOT SCARED and when i wanted to touch him,he read my mind and touched my head.we found ourselves in a strange place ,where i saw a lot of people like him.i asked him who those people were and he said this to me,'all these you see are souls of dead people.so i said,'what are they doing outside here instead of resting in their graves,he said,'these souls have nothing to do,they are awaiting GODS judgement.so i asked him,what do they do to the living?'he said,We torment the living and bring great sadness in their lives.so i said,but why don't u bring the same sadness to me?he then showed me a picture of myself praying to Allah.and showed me a picture of my family and my( ex boyfriend before i changed my religion).we were enclosed in a shell,the souls were trying to enter but were failing,then he said,'you are always praying to Allah,that shell u see around all of u is the protection of Allah,he always shields u and those u pray for.then he said,u even pray for your ex boyfriend who brought much pain to u.so i told myself that its very very important to pray for others.then he took me to lonely soul,she was looking down and crying.so i asked why she was crying then he showed me a man and his wife,and two(2) children(sited in a corner crying,)so i asked him who those people were then he said,'the woman u have seen is the younger sister to this one who is crying.instead of taking care of her late sisters children,she gets married to her late sisters husband and starts making the children suffer.so i asked him saying'u said these souls of the dead torment the living,why doesn't she do the same to the sister.SO HE SAID.AM SHOWING YOUR ALL THIS BECAUSE I WANT YOU TO BE PREPARED.YOU SHOULD KNOW THAT WHEN U COME TO THIS LAND,THERE IS NO WAY GOING BACK TO MAKE THINGS RIGHT AGAIN,SO MAKE EVERYTHING RIGHT WHEN U ARE STILL ALIVE,DO GOOD THAT U WILL NOT COME AND JOIN US.so i asked him,but how long are u going to be here?he said ONLY ALLAH KNOWS THE DATE,IT MAYBE TOMORROW OR HUNDREDS OF YEARS FROM NOW.BUT BE ON YOUR GUARD.DO GOOD.i was shown a lot of things but this is all i remember,i wish i can remember more,but MY QUESTION IS WAS IT A VISION O WHAT?
