I write this as a warning.
When I was 18 me and a girl I knew collected some datura leaves and flowers from a house close to my flat at the time, we boiled it up as a tea had a cup each, not much happened just lost ability to focus, when reading words blurred into one big ink puddle, she reported the same.
A few days later I boiled up some left over leaves and drunk an unknown amount, I sat down and just watched TV. A hour or so later I picked up my playstation controller and started playing street fighter, after awhile I thought that's strange the fireballs are crossing my lounge then POP it disappeared(I should note now I didn't have a playstation at the time). Confused by this I went back to watching TV. Same thing happened playstation-fireballs-POP. All gone again this happened several times.
I started talking to the guy in full army gear that was standing in my kitchen, at the time this seemed a perfectly normal thing to happen, POP he disappears.
One by one people where turning up to the party I was chatting away with people and POP there gone so I'd talk to the next person, when they disappeared I'd simply move on it was what I thought was normal never struck me as odd.
Then a real person turned up who I think for my protection suggested I go to his place with him, we got a taxi and on the way I vividly remember a truck in front of us when that POPPED I recall talking about it and getting mad that the taxi driver didn't see it I thought he was messing with me. I was not happy but shrug it off, when we reached my mates house somehow I lost him and went to what I thought was his place I was banging on the window people kept telling me to leave they were being real rude in my opinion. But I left and decided I should go home(about a one hour walk).
Just down the road I recognized some people in a car and knocked on the window cause they weren't looking at me, they wouldn't wind it down, I got sick of waiting and went back to walking, I seen someone else I knew went over had a chat then POP its a lamp post further down the road I see someone else I knew started talking then POP its a bush a tree a lamp post. Over and over people I know, talk with them then POP gone.
When I get to the road down by the harbor I keep seeing people I know walk into the water I go to follow but the sharks scare me to much there far braver than I, Then I'm back talking to bushes and trees.
Eventually I get to the train station its all clear I decided to take the short cut, half way across the tracks they start yelling watch out get off the tracks, there are trains everywhere I freak out and sprint to the fence I'm safe I jump it.
After a lot more people POPPING and becoming tree/bush/lamp post I make it home with complete relief as I had started noticing how weird it was with all the POPPING, I go to bed I wake up and someone is holding me up above the bed I struggle but can't stay awake.
In the morning I wake up feeling strange starting to get faint memories I'm glad I'm now straight, People outside start talking I go out there but no one is there. Back inside It starts up again people talking but can't find them. I get a flash where I see someone out window I turn quickly but gone I'm to slow. I start getting real paranoid and confused.
Over the next few weeks the voices don't stop I got flashes of people animals objects, one night a carriage with horses steam's through my wall across the room and out the opposite wall, I see a little boy walking on my wall, my family get worried and contact the local mental health unit. I got taken in for assessment weeks had gone by they didn't think it was from the datura and I end up in hospital, I run away, cause A commotion in my confused state and get arrested after a week in jail I was transferred to the forensic psychiatric ward.
Took at least 6months to get back to a semi normal state it was a terrifying time in my life and I would warn anyone against even considering taking datura. I had no idea what was real I thought everyone was out to get me I was stuck in a seemingly endless trip.
