As this challenge plays off the previous [Inception level 3 challenge](#inception-ctf-dream-3), you should read up on that first, as it got us to this point.

From the file that was used in Inception: Dream 3, we have the following Morse Code text:

```
-.. .-. . .- -- ...
..-. . . .-..
.-. . .- .-..
.-- .... . -.
.-- . .----. .-. .
.. -.
- .... . -- .-.-.-
.. - .----. ...
--- -. .-.. -.--
.-- .... . -.
.-- .
.-- .- -.- .
..- .--.
- .... .- -

.-. . .- .-.. .. --.. .
... --- -- . - .... .. -. --.
.-- .- ...
.- -.-. - ..- .- .-.. .-.. -.--
... - .-. .- -. --. . .-.-.-
.-. .. - ... . -.-. -...- -.. .. ...- . .-. ... .. --- -.
```

```
DREAMS FEEL REAL WHEN WE'RE IN THEM. IT'S ONLY WHEN WE WAKE UP THAT WE REALIZE SOMETHING WAS ACTUALLY STRANGE. RITSEC=DIVERSION
```

Testing it out, `DIVERSION` unlocks the next levels `Limbo.7z`.

After contacting the author, the submission flag format _is not RITSEC=DIVERSION_, rather `RITSEC{...}`.

Flag is `RITSEC{DIVERSION}`.
