A bad experience in this kind of situation, where a number of total strangers are entering a meditative state together, could have been caused by anything from the place in which the meeting was held to the energies of the people involved.
This is why I recommend not doing this sort of thing with people that you don't know well.
The rule of thumb is to not enter a circle, or any other place where you will be lowering all of your shields, with other people unless you know them, love them, and can trust them.
That is what "Perfect Love and Perfect Trust" really means. Not that you must somehow blindly love and trust everyone who claims to be Wiccan; that, in my opinion is Perfect Stupidity. Lots of people who are not Wiccan in the least have found that they can use that phrase to line up easy targets for one type of unwholesome activity or another.
Sort of like a person who claims to be a relative in order to get a free meal. Well, you wouldn't fall for that, would you? You would do a bit of checking, or at least see if there was a family resemblance before you let him move in.
It's the same here. I have a number of friends who were badly burned before they learned this one.
Not that you should view everyone with suspicion and distrust; just keep your wits about you and listen to your instincts.
You knew there was something wrong with that whole thing; you were not comfortable about it from the beginning. And, in retrospect, you were right. You will find that you can save yourself a lot of grief by listening to what your feelings and instincts are telling you. They are there for a reason. Use 'em!
