Bernardo Kastrup's cosmic idealism is a type of Panpsychism according to his paper here:
This thesis articulates an analytic version of the ontology of idealism, according to which universal phenomenal consciousness is all there ultimately is, everything else in nature being reducible to patterns of excitation of this consciousness. The thesis’ key challenge is to explain how the seemingly distinct conscious inner lives of different subjects—such as you and me—can arise within this fundamentally unitary phenomenal field. Along the way, a variety of other challenges are addressed, such as: how we can reconcile idealism with the fact that we all inhabit a common external world; why this world unfolds independently of our personal volition or imagination;
The core idea of this thesis can be summarized thus: we, as well as all other living organisms, are dissociated alters of universal phenomenal consciousness, analogously to how a person with Dissociative Identity Disorder (DID) manifests multiple disjoint centers of subjectivity also called ‘alters.’ We, and all other living organisms, are surrounded by the transpersonal phenomenal activity of universal consciousness, which unfolds beyond the dissociative boundary of our respective alter. The inanimate world we perceive around us is the extrinsic appearance—i.e. the phenomenal image imprinted from across our dissociative boundary—of this activity.
So Kastrup favors a form of panpsychism according to which the whole universe is conscious and we are dissociated personalities within it, which is why we are aware only of our own consciousness. Each living organism is a fraction of the whole universal consciousness. This is also similar to Yogachara consciousness-only and some kabbalah schools of thought. As to explain how non-living objects persist even when no consciousness is conceiving of them, one way is to invoke the age-old dream analogy where you can perceive objects in it and they seem to persist during the same dream at least...
