Can I visualize with my eyes open? Can I visualize looking at my self in a scenario that I want to allow in my life while also visualizing the way I want to look? Say for instance I imagine my self traveling but I also imagine my face and body looking different? Will my mind and the universe know it's me?
Yes, if you can feel the emotions and feelings then you can do it open or closed. The reason its often suggested to do closed is because there are less distractions and your imagination can often run wild without focusing on distractions or the lack of the result.
Now when you talk about visualising the way you look, can you identify that its you in your image? If so, then thats fine, the universe will read the energy. If however you are looking at it and seeing a different person thats not you - then that will get confusing. Instead of focusing on the looks, focus on the feelings you will have when you look that way, as its an easier way to shift your vibe into that place and start creating it now.
