Somehow at the night, when i tried to make save, the game instead of just saving, teleported me to the lab (it even saved outfit) without any cutscene and heroes, and there finally i got a lockpick (When i was here for the first time, there wasnt any lockpick, which i believe breaking a proper walkthrough of dream) and thats a solving softlock of this dream. Where you need to get a lockpick in first room and then with this lockpick open a opposite room, to get a wrench with saw.
Also, this game seems like have a sort of cheat protection? I Muiltiplied amount of lockpicks with CE, and it took all of them anyway. Should just drop rest of them next time.
