I...... don't.... know...

awesomenrhSo as you may know I am a Herobrine believer so I did the ritual to summon him (survival) and to my surprise the fire went out even though it was netherrack. So I put the fire back on and the whole thing fell apart... It creeped me out, so I looked behind me and I saw nothing... No Herobrine, no mobs, no houses, no nothing. So I took a break for a bit, and I felt like I had to go back on minecraft. So.... I went back on Minecraft and I was surprised when I saw a house in front of me so I went in, it was a normal house. :O I went out of the house, and walked a bit and suddenly.... A skeleton appeared out of no where (Yup.. Yup). So I killed it, and out of the corner of my eye I saw a yellow figure, I tried to go over to it but it disappeared and I was freaked out... I haven't gone back on Minecraft since then I'll keep all you guys updated as I experience this... I... I don't know.

Day 2:

So today wasn't too weird. The image of the yellow figure has been haunting me, I feel like I have to destroy it to stop it. So I didn't really notice anything different. I've heard some weird like banging sounds in my house but, I figure that I'm just paranoid after seeing it.

And as always I've been AwesomeN.....R....H

1st thing: I get the feeling some of what you said is fake, as nothing could run if you had your mc closed.
2nd thing: the yellow figure was a mob in gold armour
3rd thing: the skeleton spawned because there was cover of the trees, meaning that the mob could spawn.
