It is known fact that you will ALWAYS begin your first dream positioned on the 2nd floor (on level with the fireplace) of "Happy Moon Cottage" facing (occasionally off-center) the window.
The reason I'm making this post is because it appears that where you go from here can drastically affect the timing (for better or worse) and may influence the course of the run.

Having tried and tested these routes I can APPROXIMATELY confirm the following.
All times are estimated and use current ruling (fade to black);
Please note that there are potentially a lot more routes to be found and tested - this thread will be updated soon!

#1: Strafing backwards into the wall behind you should link you to "Happy Town" in a variable position with unpredictable linking.
This route is SLOW, typically taking anywhere up-to 3m before ending Day 1.

OR

#2: Looking down immediately upon gaining control will spawn the "Giant Baby", if you remain still you should link to the "Violence District" and be positioned on the bridge/staircase facing a warehouse unit. Running into here will spawn the "Crawling Corpse" and attempting to link with them should cause the world to shrink and for the game to play a video.
This route is SLOW, typically taking up-to 1m 20s.

OR

#3: Looking down immediately will spawn the "Giant Baby" BUT if you run forwards into the face you should link to the "Violence District" and be positioned facing a seafront. Turning around from here and running straight will take you to the manhole to jump down.
This route is OKAY, typically taking up-to 1m.

OR

#4: Running straight into the window should link you to the "Natural World" positioned facing some trees. Bearing left and running forwards will take you to the cliff edge to jump off.
This route is OKAY, typically taking up-to 0m 50s.

OR

#5: Running straight into the window BUT looking down should link you to the "Pit & Temple" positioned near one of it's corners for you to jump down. This takes a little practice to pull off consistently.
This route is FAST, typically taking up-to 0m 30s.

It is worth mentioning that Day 2 is influenced greatly by how your Day 1 concludes;
Choosing routes #1, #2 & #3 should play a video (SLOW),
choosing routes #4 & #5 should give you a text dream (FAST).

It has now been confirmed that the first link (using walls) is influenced by the amount of cinematic intros you watch before starting Day 1.

Whether this is seed orientated or based strictly on a counter is still not known for sure.

Another new strat has been found using the pterodactyl in Bright Moon Cottage that links you to the Pit and Temple being consistently available to link with on day 3 saving upto a potential two minutes.
