We never changes sides.  I wondered about this because we had two scenes of them sleeping before and both times it was the other way around. But this is only one aspect. I think there are more things that do not add up and I tend to take yesterday's tweet about "Nothing is certain. Nothing is written" as a confirmation. 
 

The stairs were there, in MHR and HLV. What was not there is the front door next to the windows (looking from the POV of the sofa). When John opens the door to the distressed neighbour in HLV, he walks to the right. The windows minus the door are to the right of the sofa. In TST we see the front door next to the windows. 

The layout in MHR and HLV is exactly the same whereas in TST the sides have been switched. 


 

I think, I' am going to like this topic very much
As I already wrote last night

IMO - that's why in the beginning and in the end of the episode we see water, and that's why in the beginning "Appointment In Samarra" story is told - initially Sherlock believes, that he just avoided certain death, and he is wrong: death awaits him in UK. That's also why some moment episode becomes someway surrealistic - it is not reality, but the delusion, like in "An Occurrence at Owl Creek Bridge" by Ambrose Bierce.
My only doubt is because similarity between this story, and TAB - delusional Sherlock, again?
But except this, everything seems to fit perfectly together...

I guess, there are many mirrors in this episode as the symbol, because what we see in the second half, is just reflection of reality in Sherlock's mind. Switched details - the same. Switched bedsides - Sherlock probably was never in Watsons bedroom, and surely he never was able to see both of them in the bed. He needs to imagine such details, and has only 50% chance to do it right.
IMHO sharks symbolize the danger (this water can kill!), and also are the reminder of CAM. And what happens after the pool scene, is projection of Sherlock's consciousness, and subconsciousness - we can deduce some very interesting facts, like what he feels about John and Mary. 
Of course, I believe, that Sherlock is to be saved very soon!

To be honest, I hope most of the episode - and the future ones - take place in the real world. MP was cool the way they used it in TAB, but they shouldn't do that too often.

I agree completely. I simply cannot find another way to make all pieces of the puzzle fit so good...
On the other side: I hoped Mary to last in "Sherlock" some episodes longer - maybe as the recurring character? With her past, she could be made to disappear, and return next season. She kept bringing great energy to the series. So, that's the reason, why I would like her to not die so soon.

I like MP most in the way it was shown in HLV after the shot. That was brilliant. But whole episodes in MP are far too much for my taste.

I hope by far most of what we see is real. TAB was fun and kind of made sense in the way it connected Victorian times to the present. But if everything is a dream/MP etc. it would undo the character development we see and mean that actually nothing is at stake. There already is a problem in the story that even death feels only semi-permanent, thanks to all fake deaths/implied fake deaths. I personally prefer the dead to stay dead and MP to be used sparingly. The stakes are higher this way.

As far as TST is concerned I do think most of what we are seeing is "real."  But that we are seeing it from the point of an unreliable narrator.  I lean toward the idea that most of what we see in the episode is Sherlock relating the events to Ella in therapy.  This makes the most sense to me.   

Well, a big part of me would like it, if we still are in MP or something like that, if, in the end, they manage to pull that off cleverly. And at this point I have doubts. Too much has happened storywise since HLV (and before).
And it wouldn't bring the story forward, would it?

This whole episode had a weird feeling to me, I wasn't very pleased with it. It was weird in a different way from TAB or some scenes in HLV for example. I don't see the episode being mindpalace, still it had a dreamlike, irritating quality. Maybe because it raised more questions than they have answered.
