A bad trip is not as self-evidently defined as you make it seem ^^ what it means to you exactly can differ subtly or hugely from what others think of it. So I think blanket statements like that are less than unhelpful. Have some nuance and join the discussion in the '
Big & Dandy Bad Trip Thread' and subthreads if you think you have something intelligent to say about it.
Regarding questions such as what this thread is based on / the OP, it can be hard for others to decide for you what to do and in principle this forum is against placing such decisions in the hands of others. Even possible advice is limited.
I guess you first would need to figure out a bit better if what happened to you was mostly because of mindset or because of setting. (
Check this B&D Set & Setting Thread!)
If it is because of mindset then maybe you need to develop some things more in life before tripping more, or you are just not cut out for it (for example people who are on the hysterical side may be better off avoiding psychedelics, if I can generalize for a second). Or there are ways to prepare yourself better for a trip (
we also have a megathread for trip preparations), check the Psychedelic Index for more related threads. The set may include choosing another psychedelic to see if LSD approaches psychedelia in a way you don't really like or tolerate well.
Bringing us to the setting: if the situation was just not right for you, then this requires attention if you want to trip again. IMO it sounds like the setting was wrong at the festival like I said before.
Or rather than something being plain wrong it can also be that there was a mismatch between dose, or the drug, and the event. For some applications or activities a different dose is better compared to other ones.
Don't get hung up
too much on what went wrong, it might be locked inside memories or you might not be able to solve that riddle, but instead you can just give it some time before you try again, meanwhile reading up on all these aspects and doing a lot of research using trip reports and sites like these and Erowid... EB has suggested something similar and I'd agree (although the history of LSD is not really that necessary IMO. That would mostly shape expectations, I find it better to just let it be what it is, not what others have been saying it is for decades).
