and tell them them while they’re dreaming even when they arn’t lucid, tell the mthey’re dreaming and make them lucid?
It depends if you believe in shared dreaming or not! Never been proven or disproved, will not be for a long time! You can try and ask the person the next morning. There’s been some people on this forum offering some degree of proof that it exists, but of course we can’t know for sure. Some say it’s coincidence, others say it’s fact, and many are in the middle waiting for confirmation from ze labs.
YES! This can be done easily. Me and my friend used todo this alot, and it works incredibly great. It actually started with my friend telling me, that he could alter his girl friends dreams - while he was awake, and she (ofcause ?) was dreaming. He could start to speak to her, and she would respond in eye ticks and moving - somtimes speak.
I have also read the post stating that sleeping on eachother helps a lot:)seriously,just cant find it:)
and no it wasnt mine:)
Wow, for some reason I thought he was talking about shared dreaming. Whoops. Of course you can do it. But you have to be doing it right. Too loud will wake them up, too soft they won’t hear it, and the person has to be trained to remember they are dreaming. You can do it yourself with a cd/tape player while you are asleep. just forward about 15 mins and then start repeating “you are dreaming” with increasingly loud volume, until you are sure you’ll hear it, then slowly lower the volume so it won’t wake you up while you are lucid. Then wait another 15 mins and start the process over. If you are still lucid by that time the second wave of repetitions come, too bad 15 mins is all you get. 
And uh, Jack…
I think I can try that.
Woodydrn, you raise a very good point, but the original post actually implies that both people are dreaming when the interaction occurs, not just one of them. As infection said, there isn’t a satisfactory amount of evidence to conclude whether or not this is possible, or to what extend people can communicate while dreaming.
It’s fairly common for people to have similar dreams, particular if they spent some time together during the previous day. For example, when I went camping with a few friends we spent the majority of a particular evening burning things in what we were destined to make the largest contained fire in our pyromaniac history. Anyway, needless to say, we all had very similar dreams on the topic of fire. Did we all share a dream? Probably not. It’s only logical to assume we would individually experience similar dreams given that we spent the entire day together, doing the same things.
Ahh i tried to do that to my mom. I was sleeping in my moms room in her bed with her cause my moms b-f was gone to cali. Well anyway she was snoring up a storm and then she said “Do you have anything you need?” and I knew she was dreaming. So I went up to her ear (Shes a VERY heavy sleeper) and said “Mom, you are dreaming…” and she didnt say anything.I kept talking to her…she just kept saying “What What What What” So I gave up 
oh and when she woke up I asked her if she heard me in her dream. she said she was at work and one of her employees told her “You are dreaming” In my voice…and she got all freaked out…
That’s so funny! 
I should try that once on someone!
