Okay... I moved from England to Wales and I live in this farmhouse there's a grave right near it and my dog will bark when nothings there and I will go into my bathroom and get a intense feeling of being watched and it causes me to feel really uncomfortable so.. is my house haunted?

It could be you scarring yourself. That is usually what happens in these situations. It really comes down to what you believe in.

It is possible. If you are bothered by it there are some steps you can take.
With regards to the property, I suggest purchasing Benedictine medals, you can find them online for less than a dollar per piece, buy 4 and bury them in the ground on all four corners of your property. You can also burn dried sage bundles throughout the house (with all windows open at the time) to cleanse the air and release any spirits who might be hanging on to the building itself.

Sage can also be easily purchased online, about five bucks.
I would also suggest you acquire some "Holy Water" from your local Catholic church, any water blessed by a priest will do. Use the water the make the symbol of the cross above each doorway in the home and repeat the St Michael prayer as you do this.

St Michael's Prayer:
St Michael the arch angel, defend us in battle,
Be our protection against the wickedness & snares of the Devil,
May God rebuke him, we humbly pray, and do thou,
Oh prince of the heavenly host, by the divine power of God,
Cast in Hell Satan, and all evil spirits who roam throughout the world
Seeking the ruin of souls. Amen.

Hope this helps. Understand these are precautions and most of the time spirits
Do not desire to harm you, only to live again or to be acknowledged.
Good Luck to you.

It's possible you have a spirit. But I wouldn't say it is haunted because of a barking dog and goosebumps. If you are uncomfortable there, talk to a local minister.
