Hi, beginner here. Just an observation: reality checks are important but non the only way to get a DILD.
Are you collecting your dream signs when you wrote down your dreams? The mirror was a clear dream sign, you didn't need to perform any reality check because you knew it already that it was a dream!
If the gravity is different, that's a dream. If the mirror doesn't reflect you precisely, that's a dream. If people, objects or texts change by looking in other direction and looking there again, that's a dream, no doubt: there is no need for a reality check. Those are reality checks on their own.

Looks to me that you are incredibly diligent and progressing so much but you're too anxious to get results. You're so close!
