My First Time using DMT

Well last night I had my first experience with DMT. My sister came to town and gave me a vape pen with a cartridge on it. She sent me home with specific instructions as to what to do and to make sure my husband was there to monitor me. I got home and took the time to meditate for a good ten minutes and open all my chakras. I have never done any psycedelic before. The most I have ever done was weed. After my meditation I dimmed the lights and made sure it was quiet and comfortable in my room. I sat in my bed and took a really huge hit of the pen and held it in for as long as i could. The moment I exhaled I felt my head get heavy...I then went in for my 2nd hit. As i exhaled I felt my eyes getting heavy. As hard as it was I took one more hit and thats when I felt the need to lay down. My husband took the vape from me once i laid down and calmly coaxed me to take another hit. So I did. I began to see nothing but blinking colors and geometrical patterns that started to dance. I slowly felt my body fading away. Everytime i relaxed a muscle more of me would disappear. I had to keep convincing myself to let go and let whatever happens happens. The trip lasted for 7 1/2 minutes. I never saw anything else. I do not believe I had my breakthrough yet. My sister informed me I was just in the tunnel. Shes encouraging me to try it again.
