OK, I fully expect the more experienced to give me a well-deserved "Lighten up, Francis" here, but here goes:

I'm brand-new to the hobby, just had my first experience two days ago.  The provider could not have been better - professional, pleasant, etc.  I plan to write an extremely favorable review.  But during and since then, I have had overwhelming feelings of dissociation - feeling completely detached from the experience.  It's been 48 hours, but I barely remember a thing from that day.

Perhaps a defense mechanism to deal with the stress of the event (I'm a bit high-strung, and was very nervous)?

Has this happened to anyone else?  Did it get better with experience?
