It's one of the reasons why I really enjoy the occasional psychedelic trip. I find that it makes me much more present in the moment, and in my body.

For instance, I am prone to not noticing how I feel, whether that's pain, temperature, tiredness, etc.. I need to manually check in with myself and basically ask "am I hungry right now?", and then ponder that for a moment. Often, once I do, I am hit with sudden and extreme hunger that I am only just feeling, despite not having eaten for a long time. Or when it's too warm, I might only notice that I'm overheating when I say something unkind due to heat making me grouchy, or when I feel like I'm about to pass out.

When I am tripping however, responding to basic needs demands my full attention. I might suddenly feel an extremely strong instinct of "I need to be warmer, and I need it now" — and because I am a responsible tripper, there is usually an assortment of warm cozy things to hand, should I need them. Sometimes what I notice is more vague, like "my temperature needs to change right now, because it is not right", and I am not sure whether I'm too warm or too cold. However, I can use a blanket as a litmus test for that — if I'm too warm, when applying a blanket to myself will give a viscerally strong sense of "bad", and so I know I should open a window or get an ice pack.

I like how decisive it makes me. I find that existing in this mode for a few hours helps me to live a bit more like that in the days and weeks following the trip.
