I can totally relate to this. i have 2 dogs and they definitely act different when im tripping, specially during the peak or when i let myself go. they notice it alot on al-lad for sure, ive noticed on multiple occasions and I have always felt closer to another world that shares space with our everyday world but is unperceived most of the time.
first few times with al one of the dogs would act worried and stressed in the room i was in, and would wine occasionally.
one time on 4 hits of al we reached the peak, i was excited and full of energy moving around my place happy to BE and were slowly getting ready for a slight walk in the neighborhood. the person i was with was alot less experienced and was getting a little stuck in infinity. we continued to get ready and all of a sudden a kind of eerie song by Sounds from the Ground came on and i was into it but my companion wasnt so i changed it. it was here when the dog was starting at a specific point in the air and i was trying to see what the dog saw but it was seemingly impossible to stare directly at this out-of-focus shade of something in the air, like when looking at the heat coming off the road on a hot day, but suspended in space and kind of gray. In my head i thought 'what if we are synchronizing to a type of frequency that other form of consciousness inhabit' and got slightly closer and then felt a shock of fear or something and jumped back with a slight scream of 'aaahh!' and had super intense goosebumps. i remember it so clearly that i get goosebumps as i type this. then the dog was barking and went to hide and my companion got really nervous and I sensed a dark energy and presence in the room. like that of a seemingly dark spirit or something, and visually everything was shadowed weirdly. i now hurried for the walk and everything calmed down and went back to being jolly. that was the first time i had ever experienced something that made me think of souls, spirits, shamans, witchcraft, but understood it as concentrations of energy or like point of conscious gravity or something. very wild and very interesting. not even with dmt or something so otherwordly have i gotten those feelings.
another time i too 5 1/2 hits of al with a buddy and we have a grand ole time till he started getting lost and around now the dogs were coming up on us, licking us and wanting attention like we werent there or like they were doing what they could to keep us from 'leaving' very interesting as well.
theres been times when ive been at festivals on al and have gotten similar feelings out of the blue, making everything going on completely irrelevant, almost like entering a certain state of mind in the blink of an eye and my consciousness immediately acknowledging it without telling my body and everyday-mind first.
al is very interesting to me in that manner. and its been the trip that has most alerted the dogs. theyre pretty much normal on everything else.
ive yet to try 5 1p though
