Dream Scribble Data

Not sure what these files are for, they only seem to be used for Dreams where the main thing type is "Group". They are compressed as lz4 streams. Once decompressed:

Header

Type	Details
char[4]	Magic "brcS"
uint32	Format revision

Header is possibly longer than this

Content

Unknown, seems quite complicated. At the start there seems to be some regular patterns of 16 bytes, treating these as 4 32-bit floats yields numbers between -1.0 and 1.0, so they could potentially be positions or angles.
