Hell yeah it's all coming back. I remember those, we used to go skateboarding with them then played thps II. Really nice times. Quit the skating four years ago, went back since a few weeks... things are going nice :)
Good to hear you're alive and kicking. Marijuana is well known to make me very conscious about my heart beating. Two nights ago I had quite a bad fear, as if my heart would explode anytime due to the heavy beating. I woke up with a heartache and smoked some more that day, and everything was normal again.
I've had similiar experiences with lucid dreaming, but as you state it, drug use is most time of all the reason why I can't go through with lucidity experiments. Soon i'm planning to quit again for a while so that'll give me back my focus. The many experiences i've had however, were great. Dreams are a world on their own.
