It's O.K. - when I had these "Twilight-Zone" feelings there is nothing like it ... when trying to explain this to someone who has never suffered from it... You can't explain it to people who have never experienced it...
If it continues and starts to interfere in your life - I would not hesitate to contact your general Dr. for a visit and a referral to a psychiatrist to get a proper evaluation, if possible.
I wasted almost 2 years of my life before I had the courage to visit a Dr. because I was embarrassed and ashamed.
You may or may not need to take meds, but you should at least know what your options are...
On side note: I dealt with panic attacks for two years with no meds, (Prozac (SSRI Meds etc. were not available, and I afraid to take was not on the market yet)) - so I used various non medication techniques that at least lowered my Anxiety and OCD from a level 9-10, to a manageable level of 6-7.
Also, There are now excellent supplements - that might help, or even OTC meds I used to after reading some research on in the early 1980's - I believe it was a book: Phobia Free: A Medical Breakthrough Linking 90% of All Phobias and Panic Attacks to a Hidden Physical Problem
by Harold N. Levinson, Steven Carter. - They suggested using a OTC motion sick pill and it actually reduced (not cured) my Panic Attacks and Anxiety Fogs from full blown 9-10 levels to 6-8 used Bonine Motion Sickness tablets for over 4 years with great results... I would never have believed it... WoW !!!
Current research on Omega 3 oil supplements - (EPA Omega-3 ***** 1,000-2,000 mg) - I am reading and testing these supplements currently to see if I can use them to eventually replace some of the SSRI and other meds I am currently using.

EPA (eicosopentaenoic acid), the medium-length omega-3 molecule, is also crucial for proper brain function. There’s little EPA in the brain itself, but the molecule is able to flit in and out of neurons to help them use brain chemicals like serotonin and dopamine more effectively.

Anyways I hope this help, you are not alone! - let me know if you have any questions that I may help you with....
