Every so often I just go for it, just for the hell of it really.
Most times it's because I've taken shrooms (usually also drinking beer & Buckfast and smoking).
Usually I spend the time watching videos and listening to music. Maybe I get creative and make a few vid's, write or draw. Maybe I go wander around in the fields. Occasionally I've been known to dance, lol, thankfully in the privacy of my study, some things really shouldnt be seen in public and my dancing is one of them
And a lot of times I'm simply wrapped up in a cloud of thoughts or scrying. Most times however its a combination of all the above
The dawn is the killer though usually!
