The actor experienced something like a fugue state.

Fox was hospitalized in April last year after his 29-year-old daughter Corinne Fox experienced a "medical complication", reports mirror.co.uk.

It is believed that he later spent time in a physical rehabilitation center and has spoken about his health on a few occasions.

The actor is now believed to have further discussed the situation while speaking to a crowd in downtown Phoenix, USA recently.

According to Mirror.co.uk, footage shared on X by outlet The Art of Dialogue shows her saying, "(I was) having a really bad headache. Asked my guy for Advil." Jamie then snapped his fingers before telling the crowd, "I was gone for 20 days. I don't remember anything."

She added, "So they told me... I'm in Atlanta... They told me... My sister and daughter took me to the doctor first. (They) gave me a cortisone shot."

Pointing to his head, he said, "The next doctor said, 'There's something going on'. I wouldn't say it on camera. Yeah, I don't want to say it on camera."

This is not the first time the actor has addressed his experience.

He had shared a video message with his fans on Instagram in July last year, in which he dismissed some speculations about his health.

Jamie said at the time that he hadn't shared an update earlier because he didn't want fans to see him "running out of tubes and trying to figure out if [he's] going to make it through." "

He said his family also "didn't let anything come out" but added that this meant people were speculating.
