2 weeks ago I heard a echo voice that called out my name like 4 or 5 times , and no-one was actually calling me out!
I was in my room busy playing on my tablet on my own with the door shut. And then I heard it.
We don't have any echo rooms in our house.

Just another type of manifestation, lyssrey. With all the other posts you've made, I'm sure you are dealing with a spirit. Be careful not too get too involved into this subject. If I were you I'd look more into getting rid of these things.

But... I heard it... I know I did.
I don't know how many & what type of spirits are out in this world.
The only ones I actually know is demons but some people says that ghosts are false could you please tell me.

But I don't know how many spirits and what kind there are.
That's why am going paranolnoid now!
