I've had a lot of experiences were, usually with people I'm close to, I had the same visions as another traveler. I've communicated with people without opening my mouth. It's one of the most amazing things to me because when it happens it reminds me so clearly how we truly are one. So anyway I was pretty interested to see what others have to say about this.

..have known two people to see the same brightly lit entity, moving in the same fashion, in complete darkness on ayahuasca, with no verbal or other cues..
have no known scientific explanation...

This isn't quite a shared hallucination, but the other day I was having a Changathon with a friend and I took a fat rip and sat back - and didn't experience much... As soon as her hit took hold, I felt and saw a shock wave spread across the room and then I started tripping?! It felt like I was sort of feeding off her trip.

This was very strange for me as I usually smoalk alone, I was both baffled and impressed

Interesting Did the shockwave originate from your friend?

Recently a friend and I were tripping on smoked dmt at the same time and we both heard the same muffled voices coming from behind his head. We were unable to make out the words, but we deffinately both heard it.

I had my eyes closed, but yes, it definitely came from her direction.

About 23 years ago my Sister, best friend and myself were on acid one night.
We decided to go for a walk in the early hours of the morning and ended up walking down a long narrow path next to some woodland.
Next thing we know some huge GREEN man is running towards us down the path screaming and ripping his shirt off! Obviously we ran for our lives into the woods but we lost my sister in a ditch, she hid and we ran home to grab some sort of weapon (we lived opposite side of woodland).
On our return we found my sister where we left her and the bloke had gone. We started talking about what had happened and described him exactly the same! Even the green colour!
It wasn't the street lighting that caused the colour as we all looked normal under the same light.
We nearly got killed be the incredible HULK

We lived in a 5 story building comprised of flats at the time and when we got home there was a halo of smoke/fog encircling only our floor. Couldn't see any of the windows or anything except the rest of the building!
A very scary night was had by all

^ cjames, the fact that you are from Cornwall adds an extra degree of believability to your report..

had great mental images imagining it..

What's with cornwall?

..oh, in some traditional stereotypes the cornish, with their cider, are quite a spaced-out bunch..
it's the land of Aurthurian castles, stone circles, druidic mythology etc..
but i'm not from there, so for acuracy ask a corn..
i somehow found placing myself there added realism to the visioning of the cjames' Green Man encounter..from the feel of the place (having been there) , i could believe it's the kind of place you'd encounter one..i DO believe you, cjames!

was at a festy last summer with a bunch of friends, during the middle of the weekend we were in a car chopping up lines of something I regret doing and have since stopped, anyways as we pour the powder out of the bag bugs start crawling out from underneath it, itty bitty ant like things moving pretty fast, it was really gross. What tripped me out was that one of my friends saw the bugs too, and the other didn't. Needless to say, we didn't snort up the invisible insects, however our buddy who couldn't see them did! Now the question I am left with is... since two out of three saw the bugs, is it not that we hallucinated them, but rather that the third friend hallucinated the absence of these bugs? Crazy weekend... I don't advocate RC's by any means but if you are going to play with them... 4-aco-dmt is where it's at!

There was the time my friend and I both saw people in sensory deprivation up above us dancing and jumping, falling back into space leaving behind a trail of light and disappear.
Every time one would fall, we'd both oOooOOOOooO and AHhhHHHhhh at the same time. It would happen every 30 seconds or so. Very weird!


Then there was the time when some friends and I were sitting on the mountain watching the sunset when we heard something off in the distance. It got closer. It was people playing hokey pokey down in the valley. How absurd! Then it got closer. It was the hokey pokey looping over and over on an old speaker. It got louder. It was coming up the trail underneath us. Who knows what the hell that was. We all ran...


Then there was the time my friend and I watched a spider that we captured in a jar vanish in thin air completely impossibly disappear.


Then there was the time I dreamt of a worm in my stomach because I had a hernia and I woke up and thought about somebody in meditation and then this person contacted me concerned because they had a vision of a worm inside of me.

Yep. Weird.

..far out stories, thanks ۩..i guess there's more woods for things to hide in left where you are than in ye-olde cornwall..
i have had other multi-witness phenomena..do we have a forum x-file thread? (one without conspriracies)
.

Nen you should start one, post a link or share the name of it here.

Once when a few friends and I took LSD me and one of them in particular realized we were sharing our thoughts, I thought about my friends girlfriend, not in a sexual way just that I thought she was a really good person and wished she could have been with us. My friend looked right at me and we connected. Not just him but everyone in the room could hear my thoughts but I was totally connected to him the entire night. This startled another person in the room and just as we sensed his fear we also sensed a clicking, almost like a locust. It sounded like it came into room but felt internal, I think it was my frightend friends soul being knocked out of proportion or off its tracks as I like to say. We both looked at him and without words communicated to him it was ok and calmed him down which made the sound disappear. Me and my the other guy spent most of the night pulling strings out of and playing with our spirit like it was a puddle. The only need we had for words was to reaffirm our thoughts.
