Should I continue with Garry's Story? o wait for another Dream with Garry?

I'm not sure if I'll have another dream with Garry any time soon, I've been losing sleep, so I've been doubting... the most I've had out of Garry, was full darkness, with Garry mumbling something I couldn't hear.

Should i make up the rest of Garry's story (Until i dream of course) o should i wait entirely for the Dream?
