I remember that...

Hello everyone this time I am here to talk you about something really crazy and cool that happens to every person in the world...Flashbacks. This happens when something or someone reminds you a moment that you already lived in your past and those things that make you remember them are the most remarkable in your life, that is why you have something to make those memories come back.
I am going to tell you a little tail that will make this be more easy to understand....

The first syntom is losting the memorie but I can still remember, I have just 5 minutes but I am completely sure that I will survive because I still remember. This house reminds me the children, when the they use to play around the house, everytime that I yelled at them because of their mess, but that doesn't even matter anymore, they are dead, but I can still remember them that is a good sign I guess.
Smells awful that should be the blood of the infected ones,I would like to Have one of those coffes that she used to prepare me at tuesday's afternoon I can even remember how it tastes. I have so many doubts and I have just 2 minutes left, but I still remember, I think I am safe.
(2 minutes later) I can hear how they are coming for me, I am scared, nothing but eight bullets against forty and even more. After they come in there will be nothing but a gun with seven bullets,a bed full of blood and a man who couldn't stand this madness.

-Hope you enjoy it guys.

Here is my question:
 How do you bring back those memories you have ?
