Ecstatic experiences seizures?

Hi, I've started looking into some unusual experiences I've had all my life (I'm 35). I'm going to see my doctor soon, it'd be really helpful to hear what people think would be most relevant to mention. Some of this stuff seems so odd and vague and I didn't get a great response when I went once before after a possible seizure a few years back. Sorry it's long! As a child I had really intense deja vu experiences, these got less intense as I got older and now it's rare. I'd get this bizarre sensation and remember that I'd had a psychic dream where the exact situation I was in had played out. The dream version seemed to overlay what I was actually experiencing at the time - like I was experiencing two points in time at once and there was something I had to remember and solve. Then I'd get a feeling of massive confusion, then I'd feel ecstatic, like I'd found something incredible. I'd have phases of what I thought of as "getting my eyes stuck" on an object but I wouldn't be really looking at the object, I'd be having a really pleasant sensation but couldn’t move my eyes or respond to people. Sometimes I would see these 3D shapes in my mind that made me ecstatic and gave me information but I could still see what was going on around me. My sleep was bizarre all through childhood. I'm told I would speak to people as though I was awake but it wouldn't quite make sense, other times more strange noises or shouting and I'd make strange movements like sticking my arm up. I'd really freak everyone out by sitting bolt upright with my eyes open and screaming. I thrashed about in bed a lot, sometimes woke with large bruises, marks in the wall, fingernail marks in my palms like I'd been clenching my fists. I bit my cheeks and occasionally my tongue. I'd have phases of falling out of bed but not waking till morning. My family thought it was a sleep disorder so no one looked into it. I had extremely vivid dreams and nightmares, I also had the ecsatic experiences in dreams, but much better than while awake! After an ecstatic dream I'd have an echo of it that would last for a couple of days. I really miss these! As an adult the sleep stuff has calmed but I've had comments over the years about talking and moving around in my sleep. I've been single for a couple of years so it's hard to know what's going on. I do sometimes wake up exhausted after an eight hour sleep and last year I bit my cheeks badly on a couple of nights. Six years ago I woke up one morning feeling really odd, no one was home so it's hard to say what happened but after being awake for a long while and just lying there (but definitely not asleep) I felt really scared and then my awareness changed. I don't know if I blacked out at all first but it seemed that my consciousness had gone into a black hole, I had some awareness of my body but not much and I could notice things but not reflect on them at all. I couldn't tell exactly but it felt like my head was turned and stuck to the pillow and that I was trying to fight to move it but couldn't. I could sense some movement in my arm and leg but not sure what as I'd lost my vision. I had a sensation of my mouth opening and closing; when I came to I'd drooled on the pillow. I remember feeling terrible after and not being able to move for some time. I'd had a slightly similar experience a few years before but I was half asleep so it wasn't clear. Last year under a lot of stress I had some mental health problems, which I've experienced before. There was a lot of stuff around spiritual/ecstatic experiences while awake. Also the thing with 3D shapes that I mentioned above made a reappearance. I've started therapy and had to give a history and he showed some concern about my sleep experiences as a child, but I didn't mention everything. I'm now wondering if any of the mental health stuff could be neurological or if it's a coincidence.
