So, answering
@bloop (welcome, by the way, you certainly had a great first entry!), in two times...
I use to think that my first brush with first-hand Forteana date from when I was about 4 years old. My parents were spiritualist and mediums. Not that ever tried to have a living out of this, quite the contrary, none of them had a single dime from their gifts. So, it must be said that, at least on my experience, mediums tend to be specialized. There was once a good TV series, The Others, that portrayed this peculiarity quite well. My father was automatic writing medium (very rarely he could incorporate, too); my mother was a healing medium. And, just like what se can see on the TV series, once a week there was a reunion with some other mediums at our home, each one with their speciality. The difference was that it happened in the morning, between breakfast and lunch (so, only a sunny house, without shadowy corners and lightnings and the Hollywood paraphernalia...). I really appreciated to see the house full of people, some very interesting, some quite charming. It was because I commented with my parents about the nice lady that made me company or the bearded gentleman with the captivating smile, and, of course, because their alarmed reaction, that I understood that I couldn't quite differentiante the living and the dead during the reunions. Soon after my parents realized this, the reunions started to become more... sparse, until they ceased some time ago. I kept seeing "people" in the house for a while, dressed in white, irradiating a feeling of protection and peace, but the damage had been done, and now I feared them. Two or three years later, I could see nothing of sorts anymore.
It doesn't mean that nothing, well, out of the ordianary happened to me in my teens, for instance, but the question was quite clear...
Concerning devices like clocks and mobile phones, yes, there were some weird experiences. I remember once, in my 40s, I was wearing a wristwatch. I remember it was a period of intense emotional stress. One day, the watch had stopped, what, in itself, was unexpected, since it had been wired not long before. I didn't even cared to remove it, it remained frozen in time around 10:00am. I was waiting for a phone call, very intensely. By the end of the afternoon, the phone finally rang and the answer filled me with a feeling of intense release. Then I looked at the wristwatch. It was working. And it marked 05:00pm. There was no way I could have adjusted the time and it was not an electronic device. I had some strange behaviours from mobile phones too : turn off with no reason and a battery full, and then turning on withour even being touched. I rememeber that at least once, again on an extremely stressful moment, the motherboard of the computer I was working simply "died", without explanation or possible repair.
And, finally, concerning the effect of certain medications on the "paranormal": I only had general anaesthesics once, and, apart from this creepy sleep without dreams effect, nothing unusual happend. But since my 6 or 7 I have athsma. I took different kind of medications since then (I'm almost 57 now) and I understood at some point that they could cause sleep disturbances, like getting up from your bed and arriving in the bathroom door only to turn around and see yourself still in bed (and being suddenly pulled back to your "body"). Sometimes it happened many times in a row, until I learned to move each finger a time and "regain" control of my body. When I was not under medication (basicaly cortizone and anphetamine beta-oriented) it never happened.
There is, of course, more, but I must go back to work now...
