McLaren have confirmed that Fernando Alonso did suffer a "loss of temporary memory" in the wake of his Barcelona testing shunt.
The double World Champion hit the wall at Turn 3 on the final day of the penultimate test.
He was taken to the track's medical centre before being airlifted to hospital where he spent three nights.
Information about the Spaniard's crash has been scares leading to conjecture and speculation.
However, a report in Spain's El Pais that he woke in 1995 have been confirmed by McLaren.
According to the newspaper, Alonso told doctors: "I'm Fernando, I'm in karts and want to become Formula 1 driver."
But McLaren racing director Eric Boullier says that is normal.
He told Sky Sports F1: "It was just a normal concussion [with] a loss of temporary memory.
"It's not as dramatic as you read in the media. Everything is back to normal."
Alonso, meanwhile, has made light of the situation.
He took to Twitter to ask his 2.2million followers 'where did you wake up today'.
"In a few days the championship starts and we ran out "imagination"," he tweeted. "I propose a game with RT to the most creative. #whereDidYouWakeUpToday"
