In a shocking call to 911, a North Carolina man admitted that he thinks he may have killed his wife in his sleep. 

On the phone with the Raleigh 911 dispatcher, Matthew James Phelps, 27, said he "took more medicine than I should have." He also said he had a dream and woke up to find his wife, 29-year-old Lauren Phelps, stabbed to death.

"I have blood all over me and there's a bloody knife on the bed," Phelps said in the call on Friday. "I think I did it. I can't believe this."

Once police arrived to the Phelps home, Lauren was taken to a hospital in Raleigh and pronounced dead, WRAL reported.

Since the 911 call, Matthew has been charged with murder for fatally stabbing his wife.

Hours after the call was made, the Raleigh News & Observer published the audio. In the clip, Phelps can be heard saying, "I think I killed my..." and then trails off. 

Phelps then says he "had a dream and then I turned on the lights and she’s dead on the floor." He then mentions a knife and being covered in blood.

As the phone call becomes more emotional, Phelps tells the dispatcher he took a large dose of Coricidin Cough & Cold because "I know it can make you feel good."

According to Raleigh booking records, Phelps is being held without bail on one count of murder.

Matthew and Lauren Phelps married last fall and posted photos on Facebook of their Star Wars themed wedding. 

Bayer, the company that manufactures Coricidin Cough & Cold, released a statement about Lauren’s death.

"Bayer extends our deepest sympathies to this family. Safety is our top priority and we continually monitor adverse events regarding all of our products,” Bayer said in a statement to BuzzFeed News. "There is no evidence to suggest that Coricidin is associated with violent behavior."

A memorial fund for Lauren Phelps has been started by her friends and family.
