First image?

So, I was using a binaural beat to achieve clauriaudience (after I did some guided meditation to open the third eye with a video recorded by a woman with a lovely voice; after, after meditating on three different sigils today, with breaks between everyone of them).

I was actually pretty relaxed, hearing the sounds, trying to find something different and then… this image of a white pen popped into my mind. For no reason. Now, I know there is a train of thought. The thoughts non-related to what I’m doing come from somewhere, even if it is symbolic. But this came out of nowhere. Nothing.

In case it means anything, I am (or try to be) a writer.

Was that just a random image that popped up on my mind just because? Or it is a sign that the third eye is opening?

I’m kind of confused here.
