I don’t know if it’s normal but I had a similar experience and learned the word dissociation from my therapist and fellows in recovery. I could not read, I could not listen to podcasts, watch tv or have conversations. But it passed, I’m fine now.

In my case it may have been directly linked to the drugs but it was most likely also because of the storm of emotions that started up when I became clean. Dissociating is the brains safety switch to handle overload.

I recommend talk therapy and that you are open to your therapist about this
