Your graph is quite normal, albeit measured at a slightly low level. Try to measure a bit higher next time and be sure to run the REW SPL Calibrate routine to set the 75dB into REW's SPL meter (after you've set your room level).
Anyway, what looks like a horror show is actually comb filtering, which are reflections from the room's surfaces. When you measure full range, you need to apply smoothing after the measure is taken. Click the smoothing feature to about 1/3 octave, as this is more representative of how we actually hear.
The jaggedness is really too narrow to be perceived, and so to reveal the underlying trend of the signal and to show if treatments are effective, you need the smoothing feature on.
This is not the case for subwoofer measurements when creating filters for EQ's, but you're measuring full range. In that regard though, it wouldn't hurt you to take a look at the area from 50Hz-200Hz with simple axis change to your graph, so as to narrow in on any modal problems you may have to address (which hopefully would be solvable with positioning).....
