Liberty,

I think it all gets back to the point that made me write all this and search them all The episode wasn't at all realistic ;) especially it would make more sense if it was in someone's mind, wouldn't it? and especially because the writers had never written Sherlock like that, which is every trope and cliche of classical horror movies since the start, it makes even more sense for this to be some kind surreal world or a trick or something. 
haha I just like making up conspiracies XD

Apple Tree Yard is definitely gonna be an awesome show! I don't think it is fake, but BBC is acting weird over it anyway. Not much information has been put out expect of the trailer and production team. And then is Arwel talking about the wallpaper in Rosie's room? Which also has a big apple tree on it... all the other clues in the wallpaper are already in one or the other episode XD Anyway Arwel is a bit of a prankster so who knows what the heck he means! The ricktrolling was fun as well.

As for TAB I don't know... I watched it at first without knowing a thing about any theory out there and it didn't make a lot of sense... It was when I read tjlc that everything made suddenly quite a looot of sense in this adaptation and since then I've been playing with theories for bbc sherlock. However, I'm a traditional fan of the canon so yeah, I can recognise that Doyle maybe once or twice wanted to hint something else but I'll never say no to a good viewing/reading of the real stories ;)

Welcome, Sofi!  I'm sorry you were discouraged and hurt by S4 - I know some people here were disappointed, particularly by TFP.  But I'm glad you're hopeful and maybe you can find some things to like here - have a look at the Mycroft thread, for instance! 

Certainly <3 I'm loving everything here :D and of course I still love the show wholly <3

Welcome, Angel!  I see a lot of thought has gone into all that!

I won't go into every point (I might come back to it), but I just wanted to say that I think it's extremely unlikely that there's a secret episode.  Moftiss might be happy to write one, but I think the BBC would want people to watch it - so it would be publicised, not secret.  The series has finished and there is a different programme on tomorrow night at that time. 

It definitely looks as if this episode was written as an ending of sorts (although one that could be picked up and continued eventually).  It doesn't seem to be "asking" for another episode straight after.   I know some fans didn't like TFP, but some did - my feeling is that in the possibly last episode, Moftiss did indulge themselves more - insane wish fulfilment!  And not everybody liked that.   There has been similar criticism of Moffat over Doctor Who - excellent at writing, not so good with having free rein at running the show.  Personally, I loved the episode, though!

To get to your point about John being shot - Eurus wants to keep him alive, because Sherlock will save her through trying to save John.   Now, I know you can say that most of what we know about Eurus is in John's imagination!  But then ... what's the point?  We've finished off the story learning about Redbeard (something which John hadn't shown any particular interest in) and Sherlock's past and what made him what he is.  All that would be destroyed if it was just part of John's "dream". 

It also just doesn't feel like John's dream.  Why would he be so interested in Mycroft?  And there's no precedent for John using dreams/mind palace to work something out, in the way we see Sherlock in TAB. 

I'd go for 1. It's all real, and Moftiss love it!

haha thank you for reading all that XD 

about the secret episode: there are all sorts of crazy and unusual things going on highlighted in the second tumblr post I linked so you can go

Love was the context missing all along This is so cool. It is basically almost as if the writers telling us that Love was what was missing not only in Eurus but in all other Sherlock adaptations up to now. Wonder where they are going <3 

no offence intended, I am just thinking out loud XD
I had already seen the explanation of it on tumblr but this is much more concrete and helpful. Thank so much for posting it :D

aw that is wonderful <3
