Emotion recognition can be really difficult, especially if your experience of emotions early on were interrupted or messed up because of childhood trauma. I often find I dont' understand how or especially why I feel a certain way.

If you notice that these drawings are speaking to you, then they could definitely be a way for your subconcious to be communicating with you. Only you will be able to understand how/why you are affected by these drawings. Aside from dissociation, everyone has different ego states. Frued and Carl Jung are two of the biggest names when it comes to ego states. These are just different aspects of your personality, that take on different roles. With dissociation, a lot of people believe that it is just an extreme form of ego states separating themselves more distinctly within your mind. So I wouldn't necessarily put a ton of emphasis on who these figures are, and what that means, but keep drawing and see where it leads. You could take a mindful approach to the drawings and try and detach yourself emotionally while still focusing on the drawings and what they mean. (if any of these terms are confusing, google search them, and you cna learn a lot more about them).

One thing my counselors suggest is using my less dominant hand (for me my right hand because I'm left handed) to draw when I want to let my alters have a little more control. Apparently this gives my subconscious brain a little more control over the writing/drawing than it would have using my dominant hand.

Good for you for allowing these drawings to keep going, it may be a great way for you to communicate more with yourself.

With me, the way my system is set up (everyone's is different) I would think that the different figures were aspects of myself. The blue would be those parts that are feeling low, and needing more emotional support than I necessarily can offer at that time. The red would be my alter who takes on the role of the abusers in my life, and decides when I need to self harm, be punished etc. It is scary for me to learn about these parts, but since I have learned about them (especially the self-punisher) I have learned to control those urges and decide that I don't want to follow his advice to hurt myself.

For you, try and focus on what it means to you, and perhaps the knowledge will help you before you see your t again. If not, bring the issues in to your session and your t can help you make sense of it and take more control of you back.

I hope some of this makes sense, I'm feeling a bit off at the moment, but wanted to respond.
