No, your session isn't a 'normal' one but sounds as though your facilitator was not in the right frame of mind/being to be supportive of someone elses inner exploration. The session is for the client and not for the therapist unless that is a pre arranged intention.
Dolores's training was incomplete in that a lot of people without any therapeutic training learned her technique but do not understand hypnotherapy or hypnosis. Originally Dolores only trained professionals in the field and then she changed it to include everyone. Some people are natural therapist due to soul/past life experiences so it can work out beautifully, but others should at least take some basic training to ensure the quality and integrity of the work.
What's showing up a lot lately is that people have attachments or other intrusions and its THEIR past lives or so called SC communicating. Dolores didn't believe in negative entities so never took precautions to ensure the sovereignty of the client. She also never explored what is the SC she speaks of.
I've learned many things from exploring the subconscious minds of numerous people over the years. Dolores died not believing in the existence of 'lost souls' or intrusions, yet still those who are affected know it to be true. I'm not saying that this is the case for you, although I've never heard someone have a voice with a different name speak through them. For that reason I've mentioned the following things. Of course there are sometimes soul names given or what a soul is known by to his/her friends or members of the soul group.
I'd recommend having another session. In the book I wrote I included a script that anyone can use. It might be that you have a friend and want to explore your inner world for fun.
I think you'll enjoy reading his book as well as the video presentation:

This doctor is a friend of mine and I refer clients to him who are affected/infected. He and his partner work remotely and it's astounding the things they find. e.g thoughtforms, alters, sub personalities, attachments etc.
