As if there wasn't enough going on in her waking life, it seems like Jennifer Aniston may have taken her daily stressors to bed with her as well.

Sources say that Jennifer Aniston has started sleepwalking at home.

The actress has recently begun walking around her Los Angeles mansion in a deep sleep and then wakes up in a different part of her home, confused and bewildered.

Friends of the 37-year-old believe she has started sleepwalking because of stress in her personal life.

The star split from boyfriend Vince Vaughn - who she met while filming "The Break-Up" - in December and pals claim she previously started wandering in her sleep when her marriage to ex-husband Brad Pitt started to disintegrate.

One pal is quoted by Britain's The Sun newspaper as saying, "She had the same problems when things started going wrong during her marriage to Brad. One time he freaked out because she disappeared for an hour-and-a-half."

Jennifer and Brad split on January 7, 2005, after over four years of marriage, amid allegations Brad had been having an affair with his then "Mr. and Mrs. Smith" co-star and current partner Angelina Jolie - who he now has a biological daughter, Shiloh Nouvel, with.

Jennifer and Brad officially divorced on October 2, 2005.
