I've meditated off and on in the past but since the new year started I do more frequently and try to do it daily.  I've noticed a few interesting things.

1.  I tend to have extremely lucid dreams on days I meditate.

2.  I’ve noticed when I’m trying to be in the moment.  I feel like I’m viewing things from my spiritual self rather than my physical self.  I’m not sure if that makes sense to anyone.  It’s a little hard to explain.

3.  When I'm trying to simply be calm and in the moment I start to see a multitude of colours in front of me.  The last time I experienced anything like it was when on shrooms.

I'm not sure if these things are normal for habitual meditation.  The last one, I wasn't sure if it was from meditating or flashbacks to my experience on the shrooms.

(I feel I need to add is was my first time doing shrooms.  One of my friends has used them way more than me and told me my experience was interesting because he had never tripped that hard on them.  I also know that there was nothing else with the shrooms)

I've also experienced number 1 and 3 ... but not sure about number 2
