HI Blue!

It must be somewhat confusing to have these experiences?

As far as I know, the hypnagogic/hypnopompic hallucinations don't usually involve thought insertion and/or psychic visions.
I am not an expert in this, however.

I am concerned about you. These experiences you'd had last night (early this morning) are the types of experiences you share with us when you are starting to experience psychosis.

What helps when you start experiencing symptoms of psychosis?

Have you had any med changes lately? Any extra stress? Been sleeping at night? Other?
You'd recently reported having been upset about "bad" memories . Do you think this might be playing a part?

I am glad you have reached out, asking for input. Others may be along with a different perspective to offer.

I hope you will keep an eye on things and will seek additional help if wanted/needed.

Much Love
