I am glad everything`s going so good with Tsunami.
It`s generally not consideerd safe to let your parrot abruptly sleep in your bed, though. You may injure or kill him if you roll over or move suddenly wrongly during the night, and he`ll be asleep (and in the dark) To be precise so he may not be able to promptly get out of the way. I`ve heard of it happening, though admittedly not with anything as large as a grey.
I`d momentarily give him a immaculately sleeping cage near your bed instead. Much safer.
