'I think I did it': Man, 28, tells 911 he awoke from dream and found his wife, 29, dead and blood all over him and blames strong cold medicine he had taken

A man calling 911 in North Carolina told the operator he woke up from a dream and found his wife stabbed to death in their bedroom.

Raleigh Police charged 28-year-old Matthew Phelps with murder Friday after he made the emergency call. When police responded, authorities say 29-year-old Lauren Ashley-Nicole Phelps was dead from stab wounds. 

In the 911 call, obtained by CBS affiliate WNCN, Phelps told the operator he took more cold medicine then he should have and woke up after his dream with blood all over him and a knife on the bed he shared with his wife.

Matthew Phelps is heard on the call saying, "I think I killed my…."

When a dispatcher asks him what happened, he says, "I had a dream, and then I turned on the lights and she's dead on the floor."

The incident happened between late Thursday night and early Friday morning at the couple's home in Raleigh (file above)

"How? How? How?" the dispatcher is heard asking.

Phelps responds, "I have blood all over me and there's a bloody knife on the bed and I think I did it."

Phelps says the medication he took was Coricidin, a cough and cold medication, "because I know it can make you feel good and sometimes I can't sleep at night."

Toward the end of the seven-minute 911 call, Matthew Phelps started sobbing, saying his wife didn't deserve this.

It wasn't known if Phelps had a lawyer.

Coricidin contains dextromethorphan and chlorpheniramine, which experts say when taken in high doses – which is typically a result of recreational use – can cause euphoria, agitation, psychoses and dissociative phenomena.

The company did not immediately return an email from CBS News' Crimesider requesting comment. A statement available on the Coricidin website describes abuse of over-the-counter products including those that contain dextromethorphan, one of the active ingredients in certain Coricidin products, as a "long-standing issue."

"When used as directed, dextromethorphan is a safe and effective cough suppressant found in more than 125 over-the-counter products and has been used for more than 50 years," the statement said.
