Consider this account of a Datura experience:
http://www.erowid.org/experiences/exp.php?ID=1825
"I suppose everyone went to bed or something cause I wandered off to the dirt road, the one that goes through the pasture. I felt energized and had control of my body now, still delirious. I had found stephen, he sat me down and began to inform of something very unnerving, the night had a very evil feeling as it was. He said 'man I don't know what to do, I don't want this.' He showed me his dark long fingernails, his face was very old and hairy (werewolf-like). I flipped out, I told him it was going to be okay and not to worry, it was just a bad dream. I knew this wasn't though I saw him, he was being possessed by her.
I ran for my life. I had begun to witness the spirit world, the darkest reality, ghost like beings were everywhere, it sickened me. I ran and ran, hopped a barbed-wire fence into a weedy field and ran around the perimeter trying to avoid stepping on snakes. I was almost flying I fell really hard at one point. When I got up I saw a glow in the middle of the field. I was controlled at this point. I was pulled to the center of the field where I witnessed some demonic action. There were seven guys and girls dressed in dark clothes, black hair, and pail skin. They were all enticed basically making love with the plant. They danced around the glowing datura plant. She was, alive. There was one guy/girl to my left that was very tall and thin he/she seemed to be the plant spirit (the leader).
They all quit dancing, Datura/she stared into my eyes and shook her head. I messed up and I knew it. I ran so quick towards the woods. He/she sent one of the others (enticed ones) after me. I tried to hop this barbed fence, but I was caught and I cut myself. I turned around and the enticed one, he stopped still in the darkness. I felt as if he wanted to run with me and get away from this evil life. I said come on dude, lets go... she'll kill you, come on! He stopped, and it was if something forced him to shake his head saying no, no. I hopped the wire and ran up the hill tore through vines, briar, just tearing through I leeped down the other side. Something stopped me and pulled my head up towards the ridge. There was the temptress, and she was after my life. She was capable of transformation and teleportation. I was so scared. I tore through the woods, I had to avoid two black jaguars. It was her, she is so so tricky and evil.
I came to the highway and it was about dawn at this point. I kept running from her. She was so tricky she had this power to dissipate, bow into the side of the road and just vanish, leaving only slightly noticeable energy particles, she could move about so quickly like this. I spent the next hour running in terror. I had to prove my strength and that I wasn't going to give in. She would offer me things like power and drugs, girls, etc. She sat on top of a road sign with her/his legs crossed behind. 'What does this say'? she tested my strength to the end. SO WICKED! I remember running, cars were swirving in order to avoid me, I guess I was in the road. I didn't dare go into the woods, they had too much power in the darker areas. I could here their evil laughter in the distance. She/he would bow into the ground every time a car would come around the corner. I was so scared and tired. I didnt know where I was but I had to get out of there quickly. "

That could have been an account of meeting the Fae centuries ago, or a modern encounter with the more malign type of "aliens". BTW, in European mythology she would be Freya
