What triggers random anxiety and panic attacks when nothing is going on?

Reminding your past memories and all sorts of bad things happened in past..and when u can't get out of it

Overwhelming emotions, or feeling a lack of control can be a trigger for most people. It tends to hit out of the blue and for no reason at all.

Well imagine that you are a coffee mug and every drop is a stressful moment. Even though at first a single drop seems like nothing, after some time goes by, it will overflow. For me, those little droplets don’t seem like much in the moment, but if you don’t get them off of your chest they will overflow.

Overthinking and being less busy and negative most people dont like to act on their decisions they only think about it and keep being delusional instead of realistic

The thoughts going on unconsciously in your head. It happens to me all the time, the random attacks that come out of nowhere.

Based off of personal experience, I've found when I am settled that's when my mind begins to overthink. Sometimes, during fight or flight, my mind doesn't have time to be anxious. It's when I'm finally relaxed that I begin to think of everything. I overthink, and therefore send myself into anxiety/panic attacks.

It can be as simple as a thought crossing your mind that sends you into a panic, like " are they laughing at me". Or the tone of someone's voice when you are talking to them. Seemingly small things are hugly amplified by anxiety and this can lead to distress and panic attacks. With anxiety there is never "nothing going on" because you always have thoughts and there is always stimulation from the outside world that can cause you to feel anxious or less to you having a panic attack. Anxiety is difficult to understand to an outsider but with the spread of awareness this can change

Well there still can be many reasons, it can be due to mood swings, hormonal changes, also overthinking is a main cause sometimes when you are maybe just sitting and you start thinking about something different but end up thinking something triggering and that can cause anxiety or panic attacks.sometime incidences happened in past which are similar to current situation or same scene viewed by you recently can be a reason too. It’s sudden but dangerous at the same time. Sometimes you might be missing someone,a old memory can cause anxiety. A sudden urge of happiness or sadness are the quiet similar reasons..

Whenever there is an unexpected change that was not something that we expected, it triggers our brain to think things are going wrong, even when they are not going any wrong and makes us anxious about the next step and if it will be also something that we not expect. Everything feels too random and stressful. (happens to me at least) and that uncertainty triggers random anxiety and panic attacks. Reminding myself to breathe and taking the change into consideration and planning further is what makes me calm random anxiety and panic attacks and helps me get more clarity about what is going on.

I can relate to having random anxiety and panic attacks. I'm not a scientist or a psychologist but the way I always rationalized it is I think our subconscious takes in information constantly and sometimes makes mistakes getting us "primed" for action. I like to imagine back in our hunter-gatherer days the subtle sound of a stick breaking behind you could be a mountain lion, or another source of danger, or nothing at all. The conscience rationalizes the noise immediately and decides to investigate or write it off, while the subconscious continues to take in more information, whether consciously written off or not or whether the "threat" is there or not and processes it to get you "primed" for action incase there actually is danger, so you can respond quickly. In modern times, our subconscious takes in information in the same way, and even though you know there isn't a threat, your subconscious may think there is, and that is where these "random" panic attacks may come from. Your subconscience priming you for action against a perceived threat. Again I have no scientific sources to back this thought, it is just how I've always rationalized it. Good luck.
