My friend was recently telling me about some strange things that have been happening to him when he was asleep. On one occasion about 6 months ago, he apparently got out of bed, went outside, got in his car, and turned the music on (not sure if he drove) while asleep. More recently, a friend asked him why he called at 3 in the morning (when he was asleep). While this is strange, the more interesting trend is this: He claims to have developed consistent dream recall suddenly and without conscious effort, that his dreams have become incredibly realistic, and that, every night, wakes up within his dream (not in the sense of becoming lucid, but actually waking up to another level of dreaming). These are strange and disparate symptoms but I’d appreciate any advice, personal experience, or completely unfounded speculation that I could pass on 
I think I have heared of things like that, I don’t remember what its called though.
I do know that it can be quite dangerous, I saw a program on TV about a year ago, was called “dangerous sleepwalkers” or something like that.
It was about some people with a simmilar things as you’re friend, one person got in his car, drived to his mothers (or mother-in-laws, I forget) house and kills her, drives back home and goes back to bed.
Than another man tryes to strangle his wife and another one killed his wife for desturbing him while fixing something near the pool, stabbed her 20 something times I think, washed off the blood and put the bloody clothes in the trunk of his car, but that may be what he always does when fixing stuff (exept killing his wife), they sayd.
I don’t know if it can be cured but I beleve some medications can help suppress it, but it would be better to talk to a doctor about that.
So, hope he won’t attack anybody and good luck

Oh, and welcome to the forum

Your friend might want to get his sleepwalking problem looked at by an expert. As Aks said, it can be potentially very dangerous.
OMG! am sorry for that. he should get help right away… cuz what Aks said is bad----
