Jennifer Aniston is usually a very private person who does not invite fans into her personal life too much.

But on Monday morning the Murder Mystery star appeared in a video where she was at ease in her Bel-Air, California mansion with her dogs.

The actress has suffered from sleep problems for decades and admitted to People that she often she worries she won't be able to fall asleep, causing stress at night. 

She added, 'It began as something that I would just accept and then all of a sudden you realize the effects of your lack of sleep and how it affects your day and your work and your mind function and your physique.'

The former Friends star went on to explain that the more she 'worries' about falling asleep, the harder it is to do so and revealed that in the past she would even sleepwalk.
