ok so my theory is that in Don't Escape 3 when the crystal goes to Sidereal Plexus they find out how to use the crystals to time travel. now in deep sleep you get notes from yourself witch could mean that you are somehow time traveling. so i think that Sidereal Plexus INC is just a front for the research facility in the future. also the quote " creating the future from our dreams" can be seen as a way to say they are "following there dreams" witch is exactly what they wand you to think. but dont take any of this to seriously sense i can,t prove anything.
other notes: the website is here http://siderealplexus.com/
i found the "Contruction" GIF here http://aviron-ic.com
Sidereal means determined by the stars or related to the stars
plexus means a network of nerves, blood vessels or just a complex structure
hey has anybody noticed all the references to sidereal plexus one. for example in dont escape 2 there is a catalog for sidereal plexus inc and if you search it you can find this website http://siderealplexus.com/ HOLY SHIT i just got what it ment by that
