When Eden star Samuel Johnson woke up in hospital earlier this year, he had no memory of being hit by a car weeks before. 

The 43-year-old Gold Logie actor and cancer fundraiser was on his way to visit family on a Saturday night in June, when he was involved in an accident which saw him suffer injuries to his head. 

Speaking about the accident on The Project on Monday night, Johnson said he "wasn't expected to survive". 

"I pulled into a slip road and went and had a wee and woke up a couple of weeks later," he told Pete Helliar.

"I wasn't expected to survive. I nearly died. My face was really a mess, basically, my whole right side was cactus. I inhaled glass."

Johnson, who spent weeks in hospital, went on to explain just how serious his injuries were. 

"I got hit between 40 and 50km/h by a small white vehicle. I broke my skull, I fractured my upper neck, and luckily my face bore the brunt of the impact, so my face saved my brain from a lot of the damage."

"Basically, I got hit fairly badly and by the time they got me to hospital, they rushed me into ICU, I tanked, and I had two loved ones with me, I was told later, that were put into the death room - the one with the fridge and the couch where you are private and you are able to be told the bad news."

The actor credits his girlfriend, Emma Rooke, for saving his life and making sure help got to him.

When he woke up in hospital, he had no memory of what happened, having suffered from traumatic amnesia. He also shared a photo of himself from the night which he also doesn't remember being taken. 

"It was weird waking up. I woke up, and I was really way more famous than I ever remembered being," he shared. 

"[I thought] photographers were trying to get at me while I was inside and I wasn't in a hospital - I was either in a mental home or my drink had been spiked. 

"Maybe I was kidnapped, maybe I was clinically insane. So, I thought all kinds of things. I was Russian for a while, I spoke with a heavy Russian accent in three-word sentences for a couple of days, and then I was a Japanese 11-year-old girl... Basically happens when your brain gets wobbled is you go loopy."

Johnson says he's still in the process of recovering. 

"Whilst I appear to be ok, a lot of the symptoms are now invisible. But I'm still injured and I'm still recovering."
