Well it sounds like you had an experience of a level of intensity you weren't expecting. Since your coping abilities can't match it stuff happens around you that is out of your control. When negative associations are made - I definitely have experienced the devil projection - then it can really feel like you are lost in a fairytale gone haywire. Calling this a bad trip would reflect more on the fact that you apparently don't have much experience with deeper drips plus the fact that you were not expecting one to happen at that time.
Which means you have caused yourself to be thrown into a situation you had not planned on and had no idea yet to resolve. This can be deeply frightening, disturbing and confusing...
But there's a reason why many users of psychedelics say after a number of trips that the meaning of "bad trip" changes. Because the term implies that you are you and the trip around you is bad, victimizing you. In years of experience I have talked to people about this and they say if you start learning what set & setting really mean then you can start understanding the conditions that lead to a mental conflict that gets blown out of proportion.
You can't expect to be able to control the deep corners in your mind right away so have to creep into it in the tempo your self-reflection, self-analysis, self-awareness and self-realization become awakened. We are the deus ex machina that gradually start realizing the importance of taking responsibility for consciousness.
To come back to your story, try to see it as having a very intelligent mind that is cultivated to work behind the curtains. LSD and other psychedelics open the drapes (the doors of perception) showing us what is really going on in there and what these processes produce. But with great power comes great responsibility lol! Your mind is an incredible thing that takes a lot to control consciously!! Which is why there is conditioning, making us behave like we have programs installed to do the hard work for us so that we only have to concern ourselves with the utmost endresult, the top layer interface we call reality. But, is it real or is it a mockup version of the actuality? If you look at it like this, probably more we experience is an illusion caused by ego-instructed conditioning than not. It's a healthy protection mechanism so that we can survive and adapt but that is a long way from doing what you truly and deeply intend.
LSD can decondition you, giving the power back in to your own hands. You are detecting much more information to be interpreted and if you have not developed a way to deal with this yet you will become extremely susceptible like an infant. Agreed? So you will need to learn a whole new way of living, now growing up using conditioning as handlebars so that you can process it unconsciously, no now you will have to really truly work things out for yourself. If it is forced upon you and terribly fast, yes no wonder one might call it a bad trip. But looking at the big picture it is a learning opportunity to step aside and take matters into your own hands!
The so-dubbed awakening of consciousness or awakening of intelligence is basically a life's work for billions of souls across the globe. But there are of course those that picked up the scent of enlightenment and become enthousiasts maybe even devoted to the deus within!
