The Energy Between Us

Why Some People Feel Comfortable and Others Don’t

Recently I noticed something during a conversation with a family member. Nothing particularly dramatic happened, yet I could feel a subtle tension arise in my body. My nervous system seemed to register something before I consciously understood it.

Later I found myself reflecting on that moment and wondering about something familiar in human relationships. Why do some people feel immediately comfortable to be around, while others create a quiet sense of tension even before we know them well?

Most of us have had this experience. We meet someone for the first time and something in us settles. The conversation flows easily. There is a sense of ease that feels difficult to explain.

At other times the opposite happens. Nothing overtly negative occurs, yet something in the interaction feels slightly strained. We may find ourselves searching for words, feeling guarded, or wishing the interaction would end sooner than expected.

People often describe this difference by saying someone has “good energy,” or that something about the interaction feels a little off. But what does that really mean?

Nervous System Cues

One possibility is that our nervous systems are constantly reading subtle cues from others. Tone of voice, facial expression, pacing, posture, and emotional regulation all communicate information, often outside of conscious awareness.

I remember a former colleague whose presence consistently left me feeling uneasy. I noticed my nervous system struggling to settle whenever I was around her. Subtle non-verbal cues such as tone of voice, posture, and facial expressions gave me a sense that I was being judged. Over time, I also became aware that she often spoke negatively about others, which reinforced the unease I was already feeling.

Reflecting on it now, I realize my reactions were a combination of her signals and my own attachment history. My past experiences sensitized me to certain patterns, and my nervous system responded before my conscious mind could make sense of it.

That experience taught me how deeply we are affected by the unspoken signals people give off, and how our own history shapes what we notice and how we react. It is a vivid example of how some people feel immediately easy to be around, while others trigger subtle tension in us even when no harm is overtly done.

“Long before we consciously evaluate someone, our bodies may already be responding to the signals they send.”

The Role of Attachment History

Attachment history is another layer that fascinates me. Early relationships shape what our nervous system interprets as familiar or safe. The emotional patterns we experienced with caregivers often become templates for how we experience closeness later in life.

Because of this, we may feel drawn toward people whose relational style resembles what we knew growing up. Sometimes that familiarity feels comforting. Other times it simply feels recognizable, even if it is not always healthy.

What we call “energy” might be a blend of nervous system attunement and attachment history.

The answer is likely a mixture of both. Some interactions may feel easy because another person is grounded and emotionally available. Other times we may be responding to echoes of earlier relationships, recognizing something that resembles our past
