SWIM was wondering this. The first time he did Diph, it was in his room at 350mgs. It was night time, and his parents were home so he was reluctant to leave his room. It was a cool trip, but he found being confined to a small space at night was bad because he hates spiders and cockroaches and kept seeing them everywhere. Also, his parents being home made me a little uneasey and he kept hearing them yell up the stairs to him as a result.(one time, he even replied. Then quickly realized what he was doing

) SWIM's second trip was when he was campign with his friends. he was outside and stress-free, and saw no spiders. But, he saw some big bugs and some of the things he was seeing were pretty weird and not-happy. Things like all his friends becoming not-happy looking big black and white cats, and his girlfriend becoming goth-looking and peirced. or his other friend having a huge bug on his face.
Now, the only happy hilight was when he was looking into the fire. Anything coming out of the fire was happy, like dolphins monkeys and other cool animals. The light seemed to be the only place where happy trips could be found.
So, i was thinking, what if a person were to take a dose of 500-600mgs in a really happy field, by a super-happy willow tree or stream? Would tripping in the light wile feeling stress free make for a much better time? or, would it be like most drugs, where hallucinations in the light are uncommon? My educated guess would be no, but i've never done it in the day. Just inside.
Anyway, some good info on this or general tips on setting would be appreciated, as SWIM is gearing p for his next journey
BTW, i dont need warnings about diph. Thanks for caring, but i always do my best to stay alive.
