What BBDoom said about feeling a buzz is pretty common. I used to feel a buzz come on my whole body, very pleasant though, like a blanket of warmth. Also ringing in the ears on the come up is common too though not uncomfortable.
One time my body felt so relaxed I thought I went toilet were I was laying lol. Fortunately not the case.
The funny thing about DMT is that you are completely lucid in the experience, not feeling under the influence the way you would with say weed or alcohol. Though a very noticeable change in how you think will become apparent but more as a realisation of forgotten truths.
People report meeting entities. All this stuff sounds pretty wild until you've experience it but once you're in it you're like ''oh, there's this'' as if plugged into the well of knowledge.
When I first met a blue entity I've had plenty of other trips feeling the presence of someone or multiple 'somethings' and can always distinguish whether they were male or female. One not so intense trip, I could feel the presence of a young girl behind me to my right while I felt the presence of a man in front of me but never saw them, just felt them.
The blue man had form though constantly shifting with no fixed state, like he was a clump of dense fractals that make up the infinite surroundings of most of what you see. He took me to a blue room where he bounced around, he was a goofy fella. I could feel a feminine energy join him as I was leaving. I later met the feminine energy as a pink blob in another trip where the same blue entity came as I was leaving.
Most of what I try to put into words only scratches the surface as with all reports. So I wouldn't try to apply too much meaning from what others experience as with other psychedelics it's very personal to where you are in your life. Though these experiences are so remarkable they are also simply in how they work, and comes with that sense of 'everything is obvious'.
Meeting entities sound scary until you feel them as part of you rather than perceive them as separate. Most of what you read will make you feel one way or another depending on the lens through which you understand these reports through.
My most intense trip was unlike any of my breakthrough experiences.
I had my first big dose by accident. There was a build up of resin which I didn't clean, I just remember the smoke being super harsh. I felt like I was in a black mist whilst being in absolute discomfort. Pain throughout my chest and abdomen, heavy behind the eyes convinced I was going to vomit. I kept calm, told myself I can do this, it will be ok. Then a glimpse of some fractals. They were very bright and vivid, 'hold up, I want to see that again' as they vanished promptly. Then as I breathed and calmed myself further everything exploded into the same glimpse of fractals, and the discomfort went. It was one of the most beautiful things I had ever seen. I felt myself feeling powerful but not in a physical or egotistical way. In a mental way, reinforcing all that I have gone through to reach that point in time, hardships I had to overcome that I forget the significance of as I balance positive and negative emotions throughout the day. After I could feel masculine and feminine energy in what felt like its purest form, and how they came together to create this new feeling of oneness and love, all whilst processing notions of how this plays out throughout the animal kingdom. I had a brief mental image of a lion but nothing I saw through the trip, it was like picturing something in your mind when in reality except, my reality was colours and fractals. Very unique visuals, unlike any of my other trips I had or was to come. A lot of what was going on felt like it was happening in a black void, with the show being all central within this void.
If you ease into a breakthrough (3 hit dose) then it should all be smooth sailing. I can only imagine this being made easier with a vape. A room with little noise and light will be your friend.
Safe Journeys✌
