Particles are waves and waves can be particles depending on how you look at them/what kind of measurement you do. I don't know what that guy means by turning inside out.
I wouldn't exactly trust government secret projects as a source of viable information.
What the heck is the difference between space time and time space? Its well known that time is another dimension of space but what this guy is saying doesn't really make any sense. Is he claiming that we can experience time inside out as in experience all time at once? If one could experience 5 dimensions I think it might be something like that.
But as of yet there is no evidence for more then the normal 4 dimensions of space and time. That doesn't mean more won't be discovered but to go on like they have already been found is taking things too far. They are being looked for though and its of course likely they could exist.
Everything is always an ocean of energy regardless of whether or not you are on DMT. Yes subatomic particles can be looked at as particles or waves but its not like the pineal gland makes the decision to look at everything as particles in our normal reality and waves in the DMT world? I dont see how it makes a difference whether or not our brain is perceiving subatomic stuff as particles or waves. If this guy is claiming that what he sais is going on prove it and don't just claim you got the information from some secret government project that no ones ever heard of. Subatomic particles are particles and waves no matter what it just depends how they are measured or what kind of mathematical formulation you put them in (Something along those lines).
Ok first of all the pineal gland doesn't secrete or even produce DMT, infact its more likely that DMT is made outside of the CNS and then gets transported in. I don't know the localization of seretonin receptors around the pineal gland but DMT acts by interacting with both seretonin receptors and trace amine receptors. I don't see why people are so hyped up on this pineal gland story when theres no evidence for it producing DMT. Infact there is more evidence for other things going on.
But let me say something about what is known about the pineal gland. Yes its very involved in sleep cycles. The pineal gland is an ancient organ and was probably in the past utilized for telling the difference between day and night. Much like it still is involved in regulating day/night cycles so it that sense it is like a 3rd eye. As far as being utilized to see into other dimensions there is no reason to think that at all really. It does make seretonin and melatonin and secretes them which does regulate sleep cycles. However I don't believe it has anything to do with astral projection or death until some solid evidence for that appears.
I think the guy who made that video is a bit out there and not really basing his claims on anything except his tripped out ideas and wouldn't take it seriously for the reasons I state above. I know I am being very critical but honestly someone has too. People can claim whatever they want and make vague connections to particle physics consciousness and psychedelic drugs but until people start putting there theories into more coherent frame works its just wild speculations.
