Was it astral projection?

Hi! I don't know if anyone is still here but if you are, could you help me explain my experience? There was a time, when i was learning how to shift realities. One night, i went to bed and tried to shift. I closed my eyes, i concentrated on my goal but i wasn't actually concentrating on a specific place where i wanted to go, even tho i had one in mind. So after few minutes, i felt like i was starting to float, and before my eyes i saw first white light, then a cloud tunnel. I was going through that tunnel with high speed, and from time to time i saw thunders. And after one minute, i stopped going through tunnel and i found myself floating in a bright, cloudy space. But all around me, up and down, from both sides i saw many portals They looked like spinning clouds with dark hole inside them. I didn't know where i was or what i was supposed to do. I knew i wasn't dreaming so my first thought was that i had to wake up. And i don't know why, but i though that going through the portal under me, was going to "bring me back" to my body. So i dived in an oh boy, what happened next was a literal horror. I woke up in my bedroom but in my family house. But it was so dark around. It looked like a scene from upside down world from Stranger things. And i was laying on my bed but i couldn't move. And i saw dark figures walking past my bed. I was loosing my conscious a few times, waking up and passing out. And i just know, they were doing something with me, i could feel the touch. After some time i could finally move, and none was around. I got up from my bed and started to walk around the house. My family was inside but they couldn't hear me. I was screaming and crying. I was so panicked. And i remember that i had like a panic attack, and because of that i accidentally threw a picture from the table and my mom saw this and got scared but still couldn't see me. So i run to my bedroom i got into my bed, and i tried to go back the same way i went in. And i saw the same bright cloud tunnel, but no matter what i always ended up waking up in this scary world. I've tried soo many times that i don't even remember the exact number. I even tried to leave the house to look for anyone or anything that could help me, but as soon as i tried to leave, i passed out and woke up in bed. I was so scared i though I'm gonna stay there forever. But I've tried one last time, but this time i was extra concentrated on leaving. And i felt i was starting to float. But then suddenly something grabbed my leg and was pulling me down. I tried so hard, i kept pushing through with my mind and i finally saw the bright light and tunnel again. And i woke up in our real world. I was shaken up, i immediately went out of my room to share this with my roommate, my hands were shaking and i didn't go to sleep that night, because i was scared that i would go there again. When i was there, it felt like hours, maybe days but in reality only few minutes passed. It's been a year now and i since then i haven't tried to shift again because i was scared. Was it astral projection? If anyone is still here, can you explain this to me anyhow?
