Signs like that tend to show up more when you’re in a receptive state, which tells me you’re more open than you might feel right now. Keep noticing but try not to attach too much meaning to any single sign, they’re guidance for your inner growth… not predictions about outcomes.
Since you mentioned wanting to work on trauma healing, shadow work is something that gets overlooked a lot and it’s often why people get stuck. Basically, it’s about looking at the parts of yourself you’ve hidden or rejected. When your twin triggers you, ask yourself what part of YOU that represents. Your twin is literally mirroring back things you need to see about yourself. I would avoid anything like the mirror exercise.
Journaling helps with this. Some prompts that actually work: “What past wounds have surfaced since meeting my twin?” and “What am I grateful for on this path, even during difficult parts?” or there’s a whole list here. Write for just five minutes. You don’t need to make it a whole thing. Seeing figures and colors during meditation sounds like your third eye is definitely opening. That will develop over time. Some people use 432Hz or 963Hz frequencies to deepen that work if you want to experiment.
