He claims his girlfriend left him after it attacked her in his home.
And he says the spooky stalker, which scrawled the word “DIE” on the inside of his window, has left him suffering from depression.
Ed, 37, said: “My ex was attacked and pinned down. I’ve had mediums come in and they’ve been attacked too.
“I’ve woken with painful scratches down my arm. I feel like I’m in real danger.
“It has destroyed my relationship and my health is still suffering quite a lot.
“I’ve woken with painful scratches down my arm. I feel like I’m in real danger”
“I’m always depressed. Once I get out of the house I perk up, but my mood drops as soon as I go back in.
“I don’t know why it seems to want me. People have said it’s not the flat that’s evil, it’s you – it’s attached itself to you.”
Ed, a paranormal investigator, believes the ghost followed him home from an exorcism.
He and a ghost-hunting team were called to rid a family home of dark forces which had allegedly been tormenting the teenage son and his friends in Horsham, West Sussex.
The events of that night were recently chronicled in the Channel 4 docudrama True Horror.
Ed said: “We didn’t like it as soon as we walked through the front door. Even the sceptics in the group didn’t want to go in.
“When it came to do the clearing it just felt wrong. There were a lot of spirits there, all very negative.
“Then this figure came up in the middle of us – I can only describe it as a circus ringmaster, dressed all in black with a big top hat and a shovel on its shoulder.
“It was just staring at us with a grin full of dirty, broken teeth.
“It was an awful experience really. You never dream of something like this happening, but it is real and it can happen.”
In the following days, Ed – who takes tour groups around haunted buildings – says friends began seeing a tall, shadowy figure in the background.
Ed even took pictures of the ghost he claims is ruining his life.
He says they show a shadowy figure lurking in a darkened corridor.
He said: “People who know nothing about it described it in detail. They were getting freaked out. Afterwards I started feeling ill.
“My mannerisms changed. I felt low, depressed, angry.”
Ed has been tormented by the hulking spirit ever since, with some experiences leaving him too frightened to sleep in his own bedroom.
He added: “Some days it disappears into the background and I think perhaps it’s gone with someone else. But it’s never far away.”
