Dreams have symbolic meanings. They often represent things that happened in your waking life that have not been resolved. If the dream is recurring it could mean something important to you remains unresolved. If you can identify the reason for your dream and understand why are having it, it can stop recurring. For example I often dreamed about falling down a a stair at my grandparents house well into my teens. When I told my dad about it, he said I had actually fallen down a stair at home when I was two years old. The dreams stopped after that. Here the dream symbol is really close to the real thing, but it could be different in your case.
“Dialing 911 in a dream is a “cry for help” and reflects feelings of concern about a period of emotional crisis. If you are dialing 911 in a dream or someone else is, identify the emergency or urgent situation you or that person wants help with in your/their waking life. Getting a busy signal, no answer, the phone doesn’t work, or you can’t dial properly, reflect feelings of frustration, difficulty or failure to communicate your need for help with an “emergency” in your waking life.” (Cmp.: www.dreamdoctor.com/index.php?option=com_dreams&c…)
So try to find out what your personal emergency could be, talk to someone about it and chances are the dreams are going to stop.
Fun fact: as my philosophy prof never failed to point out platonic friendship in the original Greek sense did not exclude sexual relations and related to a relationship between mentor and student, which meant they were homosexual in nature. Cmp.: psychologytoday.com/…/the-true-meaning-of-platoni…
You don’t really need the sever at all if you have another phone in your family that can send a text message. Now that I think of it it might not be a bad idea to set up a sever as backup. But the public sever from the developer should be fairly safe to use as well…
I’ve used a Bluetooth heart monitor worn around the chest (was around 20 $ ten years ago) to measure the heart rate before. It works well with open tracks and should be more reliable compared to a device worn around the wrist. I am not sure the gps tracker on a watch works be better than the one on your phone anyways. It might be a problem with your phone killing background apps like opentracks. Check dontkillmyapp.com before pulling the plug on a new device.
Another option would be to install an im server that is low on resources and not eating your sdcard. I think xmpp would work a lot better on a pi. Prosody, ejabberd or snikket should work nicely.
Conversions on android keeps a websocket connection open to receive messages. It’s supposed to generate very little overhead in battery consumption. The unified push app on android uses the same technique to provide other apps with pushes. So you could set conversations to be the push provider on your phone and would not need the unified push app any more. This way you would be using the same amount of battery as before.
The conversations xmpp support channel is very helpful if you have further questions: someone there will also very likely know if any apps with unified push support exist.
