How one meditation song, destoyed my entire brain

(sorry for the typo) Let me say this now, i dont know if this is a tumour or not. I dont even know what i'm dealing with. its hard to explain. But let me try it anyways... For the last few weeks i've been dealing with a lot of weird things surounding my brain or my head. It started when i was listening to meditation music online, one video was called DMT music. I was really naive, i did not knew what was going to happen. After all DMT is a drug. Anyways... when listened to the music i started to get a weird green static in my eyes. Soon later my head was swirling and the whole room was tilting and rotating. I was scared and couldn't sleep, but after 10 minutes or so i did end up sleeping! The next day i had a feeling like everything was tilting and objects were moving. I felt like the world was getting larger and people looked weird. And on the top of my head i felt a lot of pressure, It felt like my brain was expanding and about to explode. I was fearfull and had panic attacks, but in the evening it was less intense. But the next days it came back again and again. ( Btw i do not listen to that song anymore) After a few days i saw my doctor and he saw that i had vertigo. So he gave me pills for dizziness and i felt better after a week or so. But just as i thought i was recovered it came back. Now i'm stuck in a scary loop or circle. For 3 weeks i still feel the symptoms, a feeling like my head turns off for a few seconds or that i feel unreal or stuck in a dream and the world is still tilting again. My temples on my forehead get a pinching feeling. And sometimes when i wake up i get a feeling like my head is about explode. All day i feel lightheaded and i see no results. I'm constantly thinking about my symptoms and i get many panic attacks. I feel unreal and i can't seem to focus on anything. Trying to sleep is a nightmare, because i see creepy images and i get strange feelings. I'm i still high or do i have a tumour? Is my brain changed forever or will the symptoms go away? I feel like i'm about to pass out but that never happens. Does anyone know what i have?
