Reddit Finally Deciphered This Crazy Secret Message In 'Stranger Things' Trailer

But one particular mystery puzzled fans the most – the cryptic timestamps hidden in the cosmic cloud at 1:59.

Even noticing them is difficult, but deciphering them was much harder – there are four of them (1:46, :33, 2:30 and :52), but what they refer to was very hard to figure out. The first idea was to find scenes with these timecodes in the previous teasers released for the series (there were four), but it soon became clear that some timestamps were too long to be attributed to teasers.

Then came the idea to look at the trailer itself, which is long enough to feature all time markers hidden in the cosmic cloud. Fans were able to spot the right scenes but the whole picture wasn't revealing itself just yet. And then came zoeysaurusrex.

They decided to line up all the portals adjacent to each timestamp with text found in the scenes timecodes were referring to. And they cracked the enigma – the revealed message was "I am Hells Master".

Still pretty cryptic, right? Fans are yet to understand what it means, but the leading theory connects it to D&D group 'The Hellfire Club' featured this upcoming season. Or maybe it's the name of the bad guy from Upside Down shown in the trailer. As TargetWifty aptly put it "I love preseason, such a time of mysteries".

'Stranger Things ' season 4 arrives on Netflix on May 27, 2022.
