Ok I have another question concerning this... If someone, for example, smokes weed and while they're high starts to feel socially awkward and anxious, is this a reflection of how they'll feel on acid? Or is it a completely different story..?
It is a different story, but can be similliar IMO.
Anxies on acid comes and goes during the trip (mostly) - it CAN FAR more intense that the anxiety you get from smoking weed. Therefore having some benzos at hand can be very helpful when u (plan to) trip hard. Don't take them on the first signs of "horror", let it flow and change situation. This helps a lot in most cases - and just having benzos can give a secure feeling.
I also like to drink one beer while peaking (not always) - it is relaxing

On a strong trip the ability to act in a "socially normal" way will most certainly completly absent. So i would recommend not to trip first time at a rave. Better get used to acid in a place you feel secure and "home" - after getting a feeling for "navigating" it is nice to explore new places though

And most important: have fun 8)
