Is it normal to not want anyone to disturb me as i sleep in the grave?

The creeepy crawlies down there might keep you awake :o

Before you die, buy yourself a headstone that reads "Do Not Disturb" on one side and "No Moleste" on the other. Now you can rest easy.

The neighbours pool is my 'toilet', and I will pee in it, I want no one to disturb me, let me pee after I had 12 beers.

Your soul wouldn't still be bound to your body.

Any respectable person would not bother the dead so I think you'll be fine OP. Hey, if there's still a high possibility someone might disrespect your memory and grave rob you, you could always get cremated and have your ashes tossed into a body of water. Then, no one could ever disturb you. Being cremated would be better anyway then slowly rotting away in a coffin.

Eat seeds just before you die. They may sprout, and you will reincarnate into a tree of knowledge.

I don't think anybody likes being woke up.
There's been several times in the past where I've been woken up and had outbursts punching shit and yelling at the air. Now I'm prescribed tranqulizer's so I don't get as mad.

How exactly would you expect to know your remains were being disturbed? You won't be there. Nothing will be there but rotting meat and bone.
Death is not too much like sleep; you will not wake up from death. It isn't restful; it is nothingness.
